**Cautionary Note Regarding Forward-Looking Statements**

*This Annual Report on Form 10-K ("Annual Report") includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and the provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Such forward-looking statements are based on our management's assumptions and beliefs about future events or circumstances using information currently available, and, as a result, they are subject to risks and uncertainties. Forward-looking statements address events or developments that Amphenol Corporation (together with its subsidiaries, "Amphenol," the "Company," "we," "our," or "us") expects or believes may or will occur in the future. These forward-looking statements, which address the Company's expected business and financial performance and financial condition, among other matters, may contain words and terms such as: "anticipate," "believe," "commit," "continue," "could," "estimate," "expect," "forecast," "guidance," "intend," "look ahead," "may," "ongoing," "optimistic," "plan," "potential," "predict," "project," "seek," "should," "target," "will" or "would" and other words and terms of similar meaning.* 

*Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about expected earnings, revenues, growth, liquidity, effective tax rate, interest rates, anticipated benefits of certain acquisitions, financing sources, the expected timing for the closing of certain acquisitions or other matters. Although the Company believes the expectations reflected in all forward-looking statements are based upon reasonable assumptions, the expectations may not be attained or there may be material deviation. Readers and investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which they are made. There are risks and uncertainties that could cause actual results to differ materially from these forward-looking statements. A description of some of these uncertainties and other risks is set forth under the caption "Risk Factors" in Part I, Item 1A and elsewhere in this Annual Report, as well as other reports filed with the Securities and Exchange Commission ("SEC"), including, but not limited to, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. There may be other risks and uncertainties not identified in these documents (that we either currently do not expect to have an adverse effect on our business or that we are unable to predict or identify at the time of this Annual Report) that may cause the Company's actual future results to be materially different from those expressed in any forward-looking statements. Our forward-looking statements may also be impacted by, among other things, future tax, regulatory and other legal changes that may arise in any of the jurisdictions in which we operate.*

*The Company undertakes no obligation to update or revise any forward-looking statements except as required by law.*

**PART I**

**Item 1. Business**

**General**

Amphenol Corporation is one of the world's largest designers, manufacturers and marketers of electrical, electronic and fiber optic connectors and interconnect systems, antennas, sensors and sensor-based products and coaxial, high-speed, fiber optic and specialty cable. The Company estimates, based on recent reports of industry analysts, that worldwide sales of interconnect, value-add cable assembly, antenna, cable and sensor-related products were approximately $500 billion in 2025.

Certain predecessor businesses of the Company were founded in 1932, and the Company was incorporated under the laws of the State of Delaware in 1986. The Company's Class A Common Stock ("Common Stock") began trading on the New York Stock Exchange in 1991.

**Reportable Business Segments**

The Company's 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. The Company aligns its businesses into three reportable business segments: *(i) Communications Solutions*, *(ii) Harsh Environment Solutions* and *(iii) Interconnect and Sensor Systems*. This alignment and segment structure reinforces the Company's entrepreneurial culture and enables clear accountability of each of our business unit general managers, while enhancing the scalability of Amphenol's business for the future. The Company has three segment managers who lead their respective reportable business segments, each reporting directly to the Company's Chief Executive Officer. All segment information throughout this Annual Report is presented under our three reportable segments.

[**Table of Contents**](#Toc_fix)

A description of each of our reportable business segments is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Communications Solutions* – the Communications Solutions segment designs, manufactures and markets a broad range of connector and interconnect systems, including high speed, radio frequency, power, fiber optic and other interconnect products; coaxial, fiber optic, power and high-speed cable; antennas; and other products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Harsh Environment Solutions* – the Harsh Environment Solutions segment designs, manufactures and markets a broad range of ruggedized interconnect products, including connectors and interconnect systems, specialty cable, printed circuits and printed circuit assemblies and other products.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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".

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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.

[**Table of Contents**](#Toc_fix)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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 2025, the Company invested approximately $3.8 billion to fund five acquisitions, while in 2024, the Company invested approximately $2.2 billion to fund two acquisitions. Our acquisitions in 2025 and 2024 have strengthened our customer base and product offerings in many of our end markets and have brought new, high-performing management teams into the Company. On January 31, 2025, the Company completed the acquisition of the Outdoor Wireless Networks segment ("OWN") and Distributed Antenna Systems ("DAS") business (collectively, "Andrew") from Vistance Networks, Inc. ("Vistance," formerly known as CommScope Holding Company, Inc.). The acquisition of Andrew provides a wide range of products, technologies and capabilities such as communications networks solutions, with advanced technologies in the area of base station antennas and related interconnect solutions, as well as distributed antenna systems, that are highly complementary to Amphenol's existing product portfolio for next-generation wireless networks. Additionally, on January 9, 2026, the Company completed the acquisition of Vistance's Connectivity and Cable Solutions business (which we now refer to collectively as "CommScope") for an aggregate purchase price of approximately $10.5 billion, which to date is the largest acquisition in the Company's history. The acquisition of CommScope adds significant fiber optic interconnect capabilities for the IT datacom and communications networks markets as well as a diverse range of industrial interconnect products for the building infrastructure connectivity market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*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 reportable business segments), each led by a segment manager reporting directly to the Chief Executive Officer, reinforces this culture and enables clear accountability, while enhancing the scalability of the Company's entrepreneurial organization.

**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, 2025, 2024 and 2023.

The Company sells its products through its own global sales force, independent representatives and a global network of electronics distributors.

[**Table of Contents**](#Toc_fix)

with customers, the Company uses key account managers to manage certain customer relationships on a global basis so that it can bring to bear its total resources to meet the worldwide needs of its multinational customers.

**Manufacturing**

The Company is a global manufacturer employing advanced manufacturing processes including molding, stamping, plating, turning, computer numerical control (CNC) machining, 3D printing, extruding, die casting, certain other manufacturing, automation and assembly operations and proprietary process technology for connectors, specialty, fiber optic and coaxial cable production, antenna and sensor fabrication. Outsourcing of certain manufacturing processes is used when cost-effective. Substantially all of the Company's manufacturing facilities operate under certification to management system standards of globally recognized, industry certification organizations. Many of our facilities are certified to quality management systems, primarily ISO9001, but also may include ISO13485, AS9100, and IATF16949. In addition, approximately half of our facilities are also certified to environmental, energy management or occupational health and safety management systems, including ISO14001, ISO45001 and ISO50001.

The Company's manufacturing facilities are generally vertically integrated operations from the initial design stage through final design and manufacturing. 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 high 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, while allowing us to support our customers when challenges arise 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 any potential supply chain constraints. The Company sources materials and components for its products on a worldwide basis. To better serve certain high-volume customers, the Company has established 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. For a discussion of certain risks related to the Company's global operations, refer to the subsection titled "Risks Related to our Global Operations" included in Part I, Item 1A. *Risk Factors* herein.

**Research and Development**

The Company's product development strategy is to rely on product design teams at most of our business units around the world working collaboratively with customers, which often results in the Company obtaining approved vendor status for its customers' new products and programs. The Company focuses its research and development efforts primarily on those product areas that it believes have the potential for broad market applications and significant sales within a one- to three-year period. The Company seeks to have its products become widely accepted within the industry for similar applications and products manufactured by other potential customers, which the Company believes will provide additional sources of future revenue. At the end of 2025, our research, development and engineering efforts, which relate to the creation of new and improved products and processes, were supported by approximately 6,400 of our employees and were performed primarily by individual business units focused on specific markets and product technologies.

**Intellectual Property**

We own a significant portfolio of patents that principally relate to mechanical, electrical, radio frequency, optical and electronic features of interconnect, antenna and sensor products. We also own a portfolio of trademarks and are a licensee of various patents and trademarks. Patents for individual products extend for varying periods according to the date of patent filing or grant and the legal term of patents in the various countries where patent protection is obtained. 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 patents against us or any of our products. For a discussion of certain risks related to the Company's intellectual property, refer to the risk factor titled "*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*" in Part I, Item 1A. *Risk Factors* herein.

**Raw Materials**

The Company purchases a wide variety of raw materials for the manufacture of its products, including (i) precious metals such as gold, silver and palladium, (ii) aluminum, steel, copper, titanium and metal alloy products (iii) copper wire and optical fiber, and (iv) plastic materials. 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 has encountered, and in the future may encounter, difficulties in obtaining certain raw materials or components necessary for production at reasonable costs due to supply chain constraints and logistical challenges, which may include regulatory restrictions and the imposition of additional tariffs. 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 increased commodity prices 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. 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, and may in the future experience, difficulties obtaining certain raw materials and components, and the cost of certain of the Company's raw materials and components may increase*" 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**

Primary competitors include Aptiv, Belden, Corning, Foxconn Interconnect Technology, Glenair, HUBER+SUHNER, ICT Luxshare, Jonhon, Molex, Rosenberger, Sensata, TE Connectivity and Yazaki, 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.

[**Table of Contents**](#Toc_fix)

**Backlog and Seasonality**

The Company estimates that its backlog of unfilled firm orders as of December 31, 2025 was approximately $8.9 billion compared with backlog of approximately $6.1 billion as of December 31, 2024. The increase in the Company's backlog was primarily related to strong demand for the Company's products that support AI applications, as well as contributions from the Company's acquisition program. 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 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. and other countries' trade policies and other factors beyond the Company's control may adversely impact its business and operating results*," "*The Company must comply with complex export and import controls as well as economic sanctions and trade embargoes imposed by the United States government and other countries*," "*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.

**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 more than 140 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, 2025, the Company had approximately 170,000 employees worldwide, of which approximately 15,000 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.

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. 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 succession planning. 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.

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 strong culture consistent with the Company's values and to be cognizant of local circumstances and requirements, which we believe creates a high 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.

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.

The Company is focused on providing fair and competitive compensation and benefits to our employees around the world. 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.

Amphenol strives 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 employees live and work.

**Sustainability Report**

We have a shared commitment to create innovative products that enable our customers to 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 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.

[**Table of Contents**](#Toc_fix)

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 issues most significant to our business, including 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 investors, customers, suppliers, employees and members of the communities in which we operate, among others. Our 2024 Sustainability Report was prepared in accordance with 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 International Sustainability Standards Board ("ISSB") and Climate Scenario Analysis recommendations. The SASB standards and GRI and ISSB 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 and other regimes we may consider are different from, and often more expansive than, the materiality standard under the U.S. securities laws. Our 2024 Sustainability Report is available on our website at https://amphenol.com/sustainability. The items discussed in our 2024 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 "*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 other sustainability matters.*" Information included in our 2024 Sustainability Report and our website is not incorporated by reference in, and does not form part of, this Annual Report.

**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. and other countries' 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 2025, non-U.S. markets constituted approximately 65% of the Company's net sales, with China constituting approximately 16% of the Company's net sales. The Company employs approximately 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. As of December 31, 2025, approximately 79% of the Company's long-lived assets were located outside of the United States, with approximately 37% located in China. This compares to approximately 73% and 29%, respectively, in 2024. These increases relate primarily to the significant investments the Company has made to support sales of its AI-related products.

During the last few years, there have been significant changes to U.S. and other countries' trade policies, export control laws, sanctions, legislation, treaties and tariffs, including U.S. trade policies and tariffs affecting several of the countries in which we operate. The U.S. continued to impose new tariffs on imports to the U.S. throughout 2025, and in response, several countries have imposed, or threatened to impose, reciprocal tariffs on imports from the U.S. and other retaliatory measures. These changes have, in certain cases, increased our costs of doing business. There is significant uncertainty about the future of trade relationships around the world, including potential changes to trade laws and regulations, trade policies, and tariffs. We cannot predict what additional actions may ultimately be taken by the U.S. or other governments with respect to tariffs or trade relations, what products may be subject to such actions (including subject to U.S. export control restrictions), what actions may be taken by the other countries in retaliation or whether we would be able to fully mitigate the impact of any such actions by pricing or other measures. 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 or to some customers, which may result in declines in our net sales and operating income. 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 are subject to increased regulatory scrutiny and oversight. 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 government 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 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 could have a material adverse effect on the Company's business, operations, financial condition, liquidity and/or results of operations, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●postponement of customer spending, in response to tighter credit, inflationary pressures, financial market volatility and other global economic factors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●effects of significant changes in economic, monetary and/or fiscal policies, including interest rate changes by the U.S. Federal Reserve or other international central banking systems, foreign currency fluctuations and significant income tax changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●intergovernmental and other conflicts or actions, including, but not limited to, armed conflict, such as the ongoing military conflicts between Ukraine and Russia, trade wars, cyberattacks and acts of terrorism or war;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●employment regulations and local labor conditions, including increases in employment costs, particularly in low-cost regions in which the Company currently operates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●industrial policies in various countries that favor domestic industries over multinationals or that restrict foreign companies altogether;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●difficulties protecting intellectual property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●longer payment cycles;

[**Table of Contents**](#Toc_fix)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●changes in exchange control regulations or tax policy, 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●credit risks and other challenges in collecting accounts receivable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●changes in assumptions, such as discount rates, along with lower than expected investment returns and performance related to the Company's benefit plans.

***The Company and certain of its suppliers and customers have experienced, and may in the future experience, difficulties obtaining certain raw materials and components, and the cost of certain of the Company's raw materials and components may increase.***

The Company purchases a wide variety of raw materials for the manufacture of its products, including (i) precious metals such as gold, silver and palladium, (ii) aluminum, steel, copper, titanium and metal alloy products, (iii) copper wire and optical fiber and (iv) plastic materials. In the past, prices for these and certain other basic materials have experienced significant volatility. While the Company does not currently anticipate significant, broad-based difficulties in obtaining raw materials or components necessary for production, it has, from time to time, experienced certain difficulties, and inflationary pressures, increased commodity prices and regulatory restrictions 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. 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 in a timely manner 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, and for some components, alternative sources may not exist or may be unable to produce the quantities of those components necessary to satisfy our production requirements. Delays in obtaining supplies may result from a number of factors affecting our suppliers, and any delay could impair our ability to deliver products to our customers. Moreover, 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 tariffs and import restrictions, as well as pandemics and epidemics, 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 both our own information technology systems and those provided by third-party vendors to support critical business operations. These systems are subject to numerous and evolving cybersecurity threats that are designed to disrupt operations or gain unauthorized access and threaten the confidentiality, integrity and availability of our information technology systems and confidential information. 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 elevated volume of cyber threats, exploitation of previously unknown software vulnerabilities, 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. The proliferation of Internet of Things ("IoT") devices and Operational Technology ("OT") systems has expanded the potential points of entry for an unauthorized user to access a system or network. Threat actors are targeting IoT and OT systems to disrupt critical infrastructure or gain lateral access to corporate networks. In addition, the rise of AI and machine learning has led to more sophisticated and deceptive attacks. Cybercriminals are increasingly using AI-generated videos, audio and text to deceive individuals and organizations. These attacks can be used for impersonation in social engineering and fraud. Attackers can manipulate systems in new ways and more easily perform functions at scale. 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. 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.

While we maintain a cybersecurity risk management program, there can be no assurance that it will eliminate all risk in protecting our information technology systems and confidential information. We rely on third-party providers, including cloud hosting and managed security service providers, for critical aspects of our information technology and cybersecurity infrastructure. A cybersecurity incident affecting any such provider, including incidents involving our cloud hosting environments, could materially disrupt our operations, even if our internal systems are not directly compromised. While the impact of previous 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 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. Further, cybersecurity incidents could 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, fines and other penalties, 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, we outsource the storage of this data to 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. For further discussion of the Company's risk management, strategy, and governance around cybersecurity, refer to Part I, Item 1C. *Cybersecurity* herein.

In the course of operating our business, we and certain of our third-party providers collect, maintain and process data about customers, employees, suppliers and others, including personally identifiable information. We are therefore subject to a variety of laws, regulations and other requirements relating to information security and privacy, including those related to handling of personally identifiable information. The regulatory environment surrounding information security and privacy is increasingly demanding, with frequent imposition of new and changing requirements. The application and interpretation of such requirements are constantly evolving and are subject to change, creating a complex compliance environment. In some cases, these requirements may either be unclear in their interpretation and application, or they may have inconsistent or conflicting requirements. Further, there has been a substantial increase in legislative activity and regulatory focus on data privacy and security in the U.S. and elsewhere, including in relation to cybersecurity incidents. These laws and regulations impose significant obligations on companies regarding how they collect, store, protect, process and transfer personal information and can impose significant fines for non-compliance. Any failure or perceived failure by us to comply with laws, regulations and other requirements relating to information security and privacy could result in legal claims or proceedings (including class actions), regulatory investigations or enforcement actions. We could incur significant costs investigating and defending such claims and, if found liable, pay significant fines, penalties and other related costs or be required to make changes to our business. If any of these events were to occur, our reputation may be damaged, and our business, results of operations, and financial condition could be materially adversely affected.

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

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. There are climate-related risks in all of the countries in which we operate, and climate change may exacerbate certain such events and may also contribute to other changes that could also adversely impact our operations. 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 and compliance burdens, 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.

***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 anti-corruption 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.

There can be no assurance that our policies and procedures designed for complying with applicable U.S. and foreign 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.

[**Table of Contents**](#Toc_fix)

***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 various management teams. It is possible that scarce labor market conditions, which the Company has experienced from time to time, and changes in immigration policies in the U.S. and other countries in which we operate could have an adverse effect on our ability to attract, recruit, hire and retain skilled employees globally, 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 any significant 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 comparable assets and financial resources, as well as medium- to small-sized companies that have smaller portfolios or specialize in one or more of our product lines. 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, and some of the Company's end markets are subject to cyclical and at times rapid periods of reduced demand.***

The Company is dependent on end market dynamics to sell its products, and its operating results could be adversely affected by cyclical and at times rapid periods of reduced demand in any of its end markets. Demand for products can be subject to rapid changes arising from a wide variety of factors, including new technology developments, changes in general economic conditions, consolidation within an industry, changes in access to financing, competition, new legislation and regulation, an evolving global trade environment, prolonged work stoppages or other disputes with labor unions and governmental budgetary constraints, among many other factors. For example, some of our customers are making significant investments in AI, and these investments are driving robust demand for certain of the Company's products. The continued growth of this market will be dependent upon many factors, including our go-forward market share for such products, the demand for our customers' products and services, the amount and mix of capital spending by our customers, changing technology priorities and changes in government regulations and policies related to AI. Periodic downturns in any of our customers' end markets can significantly reduce demand for certain of our products and result in customers canceling, delaying, reducing or otherwise modifying their purchase commitments, 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 five in 2025 and two in 2024, some of which are large and complex. Additionally, on January 9, 2026, the Company closed the CommScope acquisition, which is the largest acquisition in the Company's history. 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 assimilating acquisitions into the Company, and acquisitions do not always perform and deliver the financial benefits expected. In addition, the Company may not be able to close acquisitions as anticipated, or at all. 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; retaining the management team; managing the response of business partners and competitors; exposure to new regions and countries, including managing the impact of particular economic, tax, currency, political, legal and regulatory risks associated with specific countries; or retaining key employees, suppliers and distributors. These transactions may also lead to litigation, and in certain limited cases, the Company has pursued indemnification claims against seller(s) of an acquired business or sought recovery under

[**Table of Contents**](#Toc_fix)

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, when 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, 2025, the total assets of the Company were $36.2 billion, which included $10.6 billion of goodwill (the excess of fair value of consideration paid over the fair value of net identifiable assets of businesses acquired) and $2.2 billion 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 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 third amended and restated credit agreement governs our $3.0 billion unsecured revolving 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", and together with the U.S. Commercial Paper Program, "Commercial Paper Programs"). The Revolving Credit Facility 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 three-year unsecured delayed draw term loan credit agreement (the "Three-Year Delayed Draw Term Loan") and 364-day unsecured delayed draw term loan credit agreement (the "364-Day Delayed Draw Term Loan" and, together with the Three-Year Delayed Draw Term Loan, the "Delayed Draw Term Loans"), each of which was entered into in August 2025. 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 or the Delayed Draw Term Loans, as applicable. Upon the occurrence of an event of default under the Revolving Credit Facility or the Delayed Draw Term Loans, the applicable lenders could terminate all applicable commitments to extend further credit thereunder (if any) 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 Delayed Draw Term Loans and such other debt instruments. As of December 31, 2025, the Company had no borrowings outstanding under the Revolving Credit Facility, the Delayed Draw Term Loans, or the Commercial Paper Programs. However, the Company borrowed $1,534.1 million under each of the Delayed Draw Term Loans in January 2026 to fund a portion of the consideration for the CommScope acquisition. In addition, the Company borrowed under the U.S. Commercial Paper Program throughout 2025, and the Company may make borrowings under the Revolving Credit Facility and the Commercial Paper Programs from time to time in 2026 and beyond.

In addition to the Revolving Credit Facility and the Delayed Draw Term Loans, the Company's various senior notes, some of which were issued during 2025, also impose certain obligations on the Company and prohibit various actions by the Company unless it satisfies certain financial requirements. While the Company was compliant with all such requirements as of December 31, 2025, there can be no assurance that the Company will remain in compliance with such requirements.

[**Table of Contents**](#Toc_fix)

***Financing a portion of the consideration of the CommScope acquisition resulted in an increase in the Company's debt and interest expense, which could adversely affect the Company's results of operations, cash flows and financial condition.***

Financing a portion of the consideration of the CommScope acquisition resulted in a significant increase in the Company's debt. This increase in debt requires a larger portion of the Company's cash flow to be dedicated to the payment of principal and interest on its debt, which could, among other things, prevent the Company from carrying out capital spending that is necessary or important to the Company's growth strategy and reduce our flexibility to respond to changing business and economic conditions. Further, the amount of cash required for the payment of principal and interest on the increased debt, and thus the demands on the Company's capital resources, have increased. More specifically, the Company expects interest expense, net of interest income, to increase from $367.8 million in 2025 to approximately $800.0 million in 2026. In addition, the Company may incur additional debt in the future that could further exacerbate these risks, any of which could adversely affect the Company's results of operations, cash flows and financial condition.

***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, 2025, 3% of the Company's outstanding borrowings were subject to floating interest rates. However, outstanding debt subject to floating interest rates will be higher going forward as a result of the borrowings under the Delayed Draw Term Loans that occurred subsequent to December 31, 2025, as discussed above. To the extent that interest rates change, our interest expense and interest payments on floating rate debt will be impacted accordingly. There can be no assurance that interest rates will not change significantly from current levels.

***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, we cannot guarantee that we will be able to maintain our current credit rating. If the credit rating agencies that rate the Company's debt were to downgrade the Company's credit rating, including any announcement that the Company's credit rating is under further review for a downgrade, 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.

**RISKS RELATED TO LEGAL AND REGULATORY MATTERS**

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

We, as well as some of our customers, 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, cybersecurity and procurement 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, many of which are complex, frequently changing, and subject to varying interpretations. 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), become subject to fines or other sanctions or prohibited from taking certain actions if we are found to have violated such laws or regulations. For example, under the executive order titled "Prioritizing the Warfighter in Defense Contracting" issued in January 2026, defense contractors designated as underperforming by the Secretary of War are prohibited from conducting stock buybacks and issuing dividends until their performance improves. As a result of the need to comply with these numerous laws and regulations, we are subject to increased risks of governmental investigations, civil fraud actions, criminal prosecutions, whistleblower lawsuits and other enforcement actions. 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

[**Table of Contents**](#Toc_fix)

countries throughout the world. Although we have compliance programs in place designed to reduce the likelihood of potential violations of these laws and regulations, our employees, contractors, or agents could violate such laws and regulations or our policies and procedures. 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 result in fines or sanctions and may have a material adverse effect on our business, operations, financial condition, liquidity, and results of operations.

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 export and import controls as well as economic sanctions and trade embargoes imposed by the U.S. government and other countries.***

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 without prior 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, as well as other countries. For example, in 2019, the U.S. government added certain companies based in China to the "Entity List" maintained by the U.S. Department of Commerce, which imposes additional restrictions on sales to such companies. Since 2019, numerous other companies have been added to that list. Further, in 2022, the U.S. Commerce Department's Bureau of Industry and Security ("BIS") 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. Since 2022, numerous other related rules and regulations have been implemented by BIS. In response to these regulations, the Chinese government has implemented its own set of import and export rules and regulations and added certain U.S.-based companies to the Chinese government's "Unreliable Entity List", which imposes additional restrictions on such companies. 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. and Chinese governments have 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 as well as audits and examinations by taxing authorities could impact the Company's results.***

The Company is subject to tax in all jurisdictions in which it operates, including the Company's two largest markets, the U.S. and China. Any tax-related audits or examinations or, changes in tax laws, regulations, accounting standards for income taxes and/or other tax guidance 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.

[**Table of Contents**](#Toc_fix)

In 2025, certain of the Company's subsidiaries based in China received notices from relevant tax authorities challenging certain of the Company's tax positions taken over up to an eight-year period. Although the Company believes its tax positions are appropriate and is currently discussing the matter with the relevant tax authorities, the Company has recorded a charge of $100.0 million in the fourth quarter of 2025. The $100.0 million charge represents the Company's current best estimate of the costs that may be incurred to resolve this matter; however, the range of potential costs is estimated to be $100.0 million to approximately $300.0 million. The Company is unable to estimate the timing for resolution of this matter.

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IRA"), a tax and spending package that introduced 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, was enacted into law. Companies were required to reassess their valuation allowances for certain affected deferred tax assets in the period of enactment but did 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 years ended December 31, 2025 and 2024. 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.

On July 4, 2025, the U.S. federal government enacted the tax and spending bill H.R. 1. This legislation contains changes to previously enacted provisions of the Internal Revenue Code and provides for extensions of certain expiring tax provisions included in the Tax Cuts and Jobs Act. Certain corporate tax provisions in H.R. 1 were enacted with retroactive effect to January 1, 2025. H.R. 1 did not have a material impact on our effective tax rate for the year ended December 31, 2025. The Company continues to evaluate the corporate tax provisions contained within H.R. 1, and the future impact of H.R. 1 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 European Union ("EU") member states have agreed to adopt these rules in two stages. The first component became effective on January 1, 2024, and the second component became effective on 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.

***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., which could result in costly product redesign efforts, discontinuance of certain product offerings or other harm to our competitive position. We cannot provide assurance that the patents that we hold or may obtain will provide meaningful protection against our competitors. In addition, we may choose to not apply for patent protection or may fail to apply for patent protection in a timely fashion. 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.

[**Table of Contents**](#Toc_fix)

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, securities laws violations, 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 diverting our management's attention, 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.

The insurance coverages that the Company maintains may not apply to all types of claims and proceedings, 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 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 and other sustainability matters.***

There is increased public awareness regarding climate change, human capital and other sustainability matters. This increased focus has led to certain international treaties and agreements and legislative and regulatory efforts. In addition to the risks discussed under the risk factor titled "*The Company may be negatively impacted by extreme weather conditions and natural catastrophic events, including those caused or intensified by climate change,*" the Company may also be subject to larger, global climate change initiatives, laws, regulations or orders which seek to reduce greenhouse gas ("GHG") emissions. In addition to government requirements, certain of our customers are also 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.

[**Table of Contents**](#Toc_fix)

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, certain governmental bodies have adopted, and are 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.

In recent years, both U.S. and foreign regulations have evolved, and there have been various new laws around the world that have been passed and will require additional related disclosure or substantive action on sustainability matters. For example, in Europe, the EU finalized the Corporate Sustainability Reporting Directive, which introduces more prescriptive sustainability reporting requirements for EU companies as well as certain non-EU companies. While in 2025, the SEC announced that it had voted to end its defense of Final Rule 33-11275*: The Enhancement and Standardization of Climate-Related Disclosures for Investors*, the litigation remains pending, which makes the ultimate outcome and compliance needs uncertain. We continue to monitor and review developing sustainability frameworks, standards, rules and regulations, including those passed by U.S. states, such as the two climate-related disclosure bills (*Senate Bill-253, Climate Corporate Data Accountability Act* and *Senate Bill-261, Greenhouse Gases: Climate-Related Financial Risk*) that will require initial disclosures in 2026. Such laws are not uniform and may be inconsistently applied, which can increase the complexity and cost of compliance as well as any associated litigation or enforcement risks.

In addition to the requirement to comply with these enacted laws and regulations and other potential mandatory requirements, any future regulatory changes in any of the jurisdictions in which we operate, in addition to those already enacted, 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 takes a risk-based approach and 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 align our Program 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 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.

[**Table of Contents**](#Toc_fix)

Our Program includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●periodic risk assessments and penetration tests, which are integrated within our enterprise risk management framework processes, designed to identify material cybersecurity and technology threats to our critical systems and information, as well as to formulate management actions to respond to, mitigate and remediate material issues (if any);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●annual management reporting to the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●reporting of the scope, objectives and results of internal audits on the procedures performed to validate the effectiveness of our control environment related to our information security systems and security controls to the Audit Committee at least two times a year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●annual cybersecurity awareness training of our employees, including incident response personnel and senior management, such as phishing simulation campaigns, to educate employees on recognizing cybersecurity threats and preventing actions that could unintentionally grant unauthorized access to our systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●deployment of endpoint protection software, supported by external managed services, to attempt to proactively detect and block malicious code from affecting our systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●a cross-functional team principally responsible for managing our cybersecurity risk assessment processes, our security controls and our response to cybersecurity incidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●the use of external service providers with subject matter expertise, where appropriate, to assess risk, monitor alerts, perform penetration testing or otherwise assist with aspects of our security controls and response to cybersecurity incidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●a documented framework and supporting processes for handling security incidents that facilitates coordination across multiple parts of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●a cybersecurity incident response process that includes defined escalation criteria that governs when cybersecurity events must be communicated to senior management and, when appropriate, to the Board within established timeframes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●evaluations and updates of our cybersecurity controls, investment in security monitoring tools, and enhancements of detection and response capabilities based on emerging threats and periodic assessments.

We have not identified risks from known cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected us to date or are reasonably likely to materially affect us. However, cybersecurity risks could materially affect us in the future, including having a material impact on 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 and security controls, and our management team updates the Board, where it deems appropriate, regarding any significant cybersecurity incidents.

[**Table of Contents**](#Toc_fix)

Our management team, including our Executive Vice President and Chief Financial Officer, Executive 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, 2025, the Company operated approximately 350 manufacturing facilities with approximately 35 million square feet, of which approximately 26 million square feet were leased. Manufacturing facilities located in the U.S. had approximately 6 million square feet, of which approximately 3 million square feet were leased. Manufacturing facilities located outside the U.S. had approximately 29 million square feet, of which approximately 23 million square feet were leased. The square footage by segment related to our manufacturing facilities was approximately 15 million square feet, 10 million square feet and 10 million square feet for the Communications Solutions segment, Harsh Environment 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.

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

*(amounts in millions, except share and per share data, unless otherwise noted)*

The following discussion and analysis of the financial condition and results of operations for the years ended December 31, 2025, 2024 and 2023 has been derived from and should be read in conjunction with the Consolidated Financial Statements and the accompanying Notes to Consolidated Financial Statements included in Part II, Item 8, herein for Amphenol Corporation (together with its subsidiaries, "Amphenol," the "Company," "we," "our," or "us"). The Consolidated Financial Statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP" or "GAAP"). The following discussion and analysis also includes references to certain non-GAAP financial measures, which are defined in the "Non-GAAP Financial Measures" section below, including "Constant Currency Net Sales Growth" and "Organic Net Sales Growth". For purposes of the following discussion, the terms "constant currencies" and "organically" have the same meaning, respectively, as these aforementioned non-GAAP financial measures. Refer to "Non-GAAP Financial Measures" within this Item 7 for more information, including our reasons for including non-GAAP financial measures and material limitations with respect to the usefulness of the measures.

In addition to historical information, the following discussion and analysis also contains certain forward-looking statements that are subject to risks and uncertainties, including but not limited to the risk factors described in Part I, Item 1A. *Risk Factors* herein, as well as the risks and uncertainties that exist with the use of forward-looking statements as described in the "Cautionary Note Regarding Forward-Looking Statements" section included herein at the beginning of this Annual Report on Form 10-K ("Annual Report").

**Overview**

*General*

Amphenol is one of the world's largest designers, manufacturers and marketers of electrical, electronic and fiber optic connectors and interconnect systems, antennas, sensors and sensor-based products and coaxial, high-speed, fiber optic and specialty cable. In 2025, approximately 65% of the Company's sales were outside the United States. The primary end markets for our products are:

The Company is also focused on controlling costs. The Company does this by investing in modern manufacturing technologies, controlling purchasing processes and expanding into lower cost areas.

The Company's strategic objective is to further enhance its position in its served markets by pursuing the following success factors:

● Pursue broad market diversification;

● Develop high-technology performance-enhancing solutions;

● Expand global presence;

● Control costs;

● Pursue strategic acquisitions and investments; and

● Foster collaborative, entrepreneurial management.

**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. The first component became effective on January 1, 2024, and the second component became effective on 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 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 reviewed the currently enacted legislation. The implementation did not have a material impact on the

[**Table of Contents**](#Toc_fix)

Company's consolidated financial statements during the year ended December 31, 2025, and it is not currently expected to have a material impact on the Company's operations, financial condition or cash flows in the future. However, the Company will continue to evaluate the potential impact of Pillar Two on the Company and its results as additional countries adopt legislation and issue individual guidance on their enacted legislation.

***2025 Compared to 2024***

Net sales were $23,094.7 for the year ended December 31, 2025 compared to $15,222.7 for the year ended December 31, 2024, representing an increase of 52% in U.S. dollars, 51% in constant currencies and 38% organically (excluding both currency and acquisition impacts; unless otherwise indicated, organic net sales growth is primarily driven by higher sales volumes), compared to the prior year. The increase in net sales in 2025 was driven by robust organic growth in the Communications Solutions segment and strong organic growth in the Harsh Environment Solutions segment and Interconnect and Sensor Systems segment, along with contributions from the Company's acquisition program, all as described below. From an end market standpoint, the increase in net sales was driven by robust organic growth in the information technology and data communications ("IT datacom") market, strong organic growth in the defense, industrial, communications networks and commercial aerospace markets and moderate organic growth in the automotive and mobile devices markets, along with contributions from the Company's acquisition program. Net sales to the IT datacom market increased approximately $4,593.7, as we experienced robust growth across a broad array of applications, in particular the continued acceleration in and strong demand for products used in next-generation AI-related applications, along with growth in networking equipment, servers, cloud storage and peripherals. Net sales to the communications networks market increased approximately $1,374.3, driven primarily by contributions from acquisitions, in particular the acquisition of Andrew (as defined and discussed below within this Item 7 and in Note 11 of the accompanying Notes to Consolidated Financial Statements herein), along with organic growth in demand from mobile network operators and wireless equipment manufacturers. Net sales to the industrial market increased approximately $770.0, primarily driven by contributions from acquisitions, along with growth in medical applications, instrumentation, alternative energy and other industrial equipment. Net sales to the defense market increased approximately $499.2, driven by broad-based strength across virtually all defense applications, particularly related to communications, ground vehicles, space, missiles and naval, as well as contributions from acquisitions. Net sales to the commercial aerospace market increased approximately $322.2, primarily due to contributions from acquisitions, in particular the CIT acquisition, along with broad-based strength in demand from nearly all commercial aircraft manufacturers across a broad range of platforms. Net sales to the automotive market increased approximately $248.3, reflecting strength in demand from both electric and hybrid drive train platforms, antenna and related assemblies, and infotainment communications. Net sales to the mobile devices market increased approximately $64.3, driven by growth in sales in handsets, wearable devices, laptops and tablets.

Net sales in the Communications Solutions segment (approximately 52% of net sales) increased 91% in both U.S. dollars and constant currencies, as well as 71% organically, in 2025, compared to 2024. The sales growth in 2025 was primarily driven by robust organic growth in the IT datacom market, with particular strength in AI-related applications, as well as strong organic growth in the automotive, communications networks and industrial markets and moderate organic growth in the mobile devices market, along with contributions from acquisitions.

Net sales in the Harsh Environment Solutions segment (approximately 26% of net sales) increased 33% in U.S. dollars, 32% in constant currencies and 17% organically, in 2025, compared to 2024. The sales growth in 2025 was primarily driven by strong organic growth in the defense, industrial, commercial aerospace and IT datacom markets, along with contributions from acquisitions.

Net sales in the Interconnect and Sensor Systems segment (approximately 22% of net sales) increased 15% in U.S. dollars, 14% in constant currencies and 13% organically, in 2025, compared to 2024. The sales growth in 2025 was primarily driven by robust organic growth in the IT datacom market, with particular strength in AI-related applications and moderate organic growth in the automotive market.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Percentages in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.

&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Net sales by geographic area are based on the customer location to which the product is shipped.

The increase in foreign net sales in 2025 compared to 2024 was primarily driven by robust sales growth in Asia. The comparatively weaker U.S. dollar in 2025 had the effect of increasing sales by approximately $84.6, compared to 2024.

The following table sets forth the components of net income attributable to Amphenol Corporation as a percentage of net sales for the years indicated.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The aggregated amount is comprised of cost of sales and selling, general and administrative expenses.

Note: Percentages in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.

Operating expenses were $17,122.7, or 74.1% of net sales, for 2025, compared to $11,938.4, or 78.4% of net sales, for 2024. Operating income was $5,868.6, or 25.4% of net sales, in 2025, compared to $3,156.9, or 20.7% of net sales, in 2024. The decrease in Operating expenses as a percentage of net sales and increase in Operating income as a percentage of net sales in 2025 were primarily driven by strong performance and disciplined cost control, which generated strong operating leverage on the significant growth experienced during the period, partially offset by the effect

[**Table of Contents**](#Toc_fix)

of acquisitions, which currently have higher Operating expenses as a percentage of net sales compared to the Company average. Operating income in 2025 included acquisition-related expenses of $181.2, comprised primarily of (i) the non-cash amortization related to the value associated with acquired backlog resulting from the Andrew and Trexon acquisitions and external transaction costs associated with acquisitions (such acquisition-related expenses aggregating $103.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $77.8 associated with the Andrew acquisition (such costs are recorded in Cost of sales in the Consolidated Statements of Income). Operating income in 2024 included acquisition-related expenses of $145.6, comprised primarily of (i) external transaction costs associated with acquisitions and the non-cash amortization related to the value associated with acquired backlog resulting from the CIT acquisition (such acquisition-related expenses aggregating $127.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the Consolidated Statements of Income). The acquisition-related expenses in 2025 and 2024 had the effect of decreasing net income by $148.8, or $0.12 per share, and $119.3, or $0.09 per share, respectively. Excluding the effect of these acquisition-related expenses, Adjusted Operating Income and Adjusted Operating Margin, each as defined below in the "Non-GAAP Financial Measures" section within this Item 7, were $6,049.8 and 26.2% of net sales, respectively, in 2025, and $3,302.5 and 21.7% of net sales, respectively, in 2024. The increase in Adjusted Operating Income and Adjusted Operating Margin in 2025 relative to 2024 was primarily driven by strong operating performance on the higher sales volumes, partially offset by the negative impact on operating margin related to acquisitions completed within the prior 12 months that are currently operating below the average operating margin of the Company.

Operating income for the Communications Solutions segment in 2025 was $3,746.6, or 31.1% of net sales, compared to $1,569.6, or 24.8% of net sales in 2024. The increase in operating margin for the Communications Solutions segment for 2025 compared to 2024 was primarily driven by strong operating performance on the significantly higher sales volumes, slightly offset by the negative impact on operating margin related to acquisitions completed within the prior 12 months that are currently operating below the average operating margin of the Company.

Operating income for the Harsh Environment Solutions segment in 2025 was $1,541.4, or 26.2% of net sales, compared to $1,093.2, or 24.7% of net sales in 2024. The increase in operating margin for the Harsh Environment Solutions segment for 2025 compared to 2024 was primarily driven by strong operating performance on the higher organic sales volumes, slightly offset by the negative impact on operating margin related to acquisitions completed within the prior 12 months that are currently operating below the average operating margin of the Company.

Operating income for the Interconnect and Sensor Systems segment in 2025 was $1,005.1, or 19.5% of net sales, compared to $825.9, or 18.4% of net sales in 2024. The increase in operating margin for the Interconnect and Sensor Systems segment for 2025 compared to 2024 was primarily driven by strong operating performance on the higher sales volumes.

Interest expense was $367.8 in 2025 compared to $217.0 in 2024. The increase in interest expense was primarily driven by higher average borrowing levels, resulting from the issuances of new senior notes during 2025 to fund all or part of acquisitions, including the CommScope acquisition (as defined and discussed below within this Item 7 and in Note 15 of the accompanying Notes to Consolidated Financial Statements herein), which closed on January 9, 2026. Refer to Note 4 of the Notes to Consolidated Financial Statements for further information related to the Company's debt.

Other income (expense), net was $99.9 in 2025 compared to $72.0 in 2024. The increase was primarily driven by interest income earned on cash and cash equivalents on hand, resulting from increased levels of cash on hand, partially driven by the issuance of the November Senior Notes (defined below) in the fourth quarter of 2025 in anticipation of the CommScope acquisition, along with increased interest rates.

Provision for income taxes was at an effective rate of 23.1% in 2025 and 18.9% in 2024. Provision for income taxes in 2025 included (i) excess tax benefits of $246.6 from stock option exercises, (ii) a discrete tax item of $100.0 related to a charge recorded for notices received by certain subsidiaries in China from relevant tax authorities challenging certain of the Company's tax positions taken over up to an eight-year period, and (iii) the tax effects of the aforementioned acquisition-related expenses during the year. Provision for income taxes in 2024 included (i) excess tax benefits of $142.6 from stock option exercises, (ii) a discrete tax benefit related to the settlement of tax audits and associated lapses of statutes of limitation, along with a difference in a non-U.S. tax filing position, and (iii) the tax effects of the aforementioned acquisition-related expenses during the year. These items incurred in 2025 and 2024 had the aggregate

[**Table of Contents**](#Toc_fix)

effect of decreasing the effective tax rate and increasing earnings per share by the amounts noted in the table below. Excluding the effect of these items, the Adjusted Effective Tax Rate, a non-GAAP financial measure as defined in the "Non-GAAP Financial Measures" section below within this Item 7, was 25.5% for 2025 and 24.0% for 2024, as reconciled in the table below to the comparable effective tax rate based on GAAP results. For additional details related to the reconciliation between the U.S. statutory federal tax rate and the Company's effective tax rate for these years, refer to Note 6 of the Notes to Consolidated Financial Statements.

Net income attributable to Amphenol Corporation and Net income attributable to Amphenol Corporation per common share - Diluted ("Diluted EPS") were $4,270.3 and $3.34, respectively, for 2025, compared to $2,424.0 and $1.92, respectively, for 2024. Excluding the effect of the items listed in the table below, Adjusted Net Income attributable to Amphenol Corporation and Adjusted Diluted EPS, non-GAAP financial measures as defined in the "Non-GAAP Financial Measures" section below within this Item 7, were $4,272.5 and $3.34, respectively, for 2025, compared to $2,382.1 and $1.89, respectively, for 2024.

The following table reconciles Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income attributable to Amphenol Corporation, Adjusted Effective Tax Rate and Adjusted Diluted EPS (each as defined in the "Non-GAAP Financial Measures" section below) to the most directly comparable U.S. GAAP financial measures for the years ended December 31, 2025 and 2024:

The increase in foreign net sales in 2024 compared to 2023 was primarily driven by robust sales growth in Asia. The comparatively stronger U.S. dollar in 2024 had the effect of decreasing sales by approximately $39.6, compared to 2023.

Operating expenses were $11,938.4, or 78.4% of net sales, for 2024, compared to $9,960.5, or 79.3% of net sales, for 2023. Operating income was $3,156.9, or 20.7% of net sales, in 2024, compared to $2,559.6, or 20.4% of net sales, in 2023. The decrease in Operating expenses as a percentage of net sales and increase in Operating income as a percentage of net sales in 2024 were primarily driven by strong performance and disciplined cost control, which generated strong operating leverage on the significant growth experienced, partially offset by the effect of acquisitions, which currently have higher Operating expenses as a percentage of net sales compared to the Company average. Operating income in 2024 included acquisition-related expenses of $145.6, comprised primarily of (i) external transaction costs associated with acquisitions and the non-cash amortization related to the value associated with acquired backlog resulting from the CIT acquisition (such acquisition-related expenses aggregating $127.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the Consolidated Statements of Income). Operating income in 2023 included acquisition-related expenses of $34.6, comprised primarily of external transaction costs, as well as the non-cash amortization related to the value associated with acquired backlog resulting from three of the acquisitions that closed in 2023. Acquisition-related expenses in 2023 are presented separately in the Consolidated Statements of Income. The acquisition-related expenses in 2024 and 2023 had the effect of decreasing net income by $119.3, or $0.09 per share, and $30.2, or $0.02 per share, respectively. Excluding the effect of these acquisition-related expenses, Adjusted Operating Income and Adjusted Operating Margin, each as defined below in the "Non-GAAP Financial Measures" section within this Item 7, were $3,302.5 and 21.7% of net sales, respectively, in 2024, and $2,594.2 and 20.7% of net sales, respectively, in 2023. The increase in Adjusted Operating Income and Adjusted Operating Margin in 2024 relative to 2023 was primarily driven by strong operating performance on the higher sales volumes, partially offset by the negative impact on operating margin related to acquisitions completed within the prior 12 months that are currently operating below the average operating margin of the Company.

Operating income for the Communications Solutions segment in 2024 was $1,569.6, or 24.8% of net sales, compared to $1,063.5, or 21.6% of net sales in 2023. The increase in operating margin for the Communications Solutions segment for 2024 compared to 2023 was primarily driven by strong operating performance on the higher sales volumes.

Operating income for the Harsh Environment Solutions segment in 2024 was $1,093.2, or 24.7% of net sales, compared to $943.9, or 26.7% of net sales in 2023. The decrease in operating margin for the Harsh Environment Solutions segment for 2024 compared to 2023 was primarily driven by the negative impact on operating margin related to acquisitions completed within the prior 12 months, particularly the CIT acquisition, that are currently operating below the average operating margin of the Company.

Operating income for the Interconnect and Sensor Systems segment in 2024 was $825.9, or 18.4% of net sales, compared to $753.7, or 18.3% of net sales in 2023. The modest increase in operating margin for the Interconnect and Sensor Systems segment for 2024 compared to 2023 was primarily driven by strong operating performance on the higher sales volumes, partially offset by the negative impact on operating margin related to acquisitions completed within the prior 12 months that are currently operating below the average operating margin of the Company.

Interest expense was $217.0 in 2024 compared to $139.5 in 2023. The increase in interest expense was primarily driven by higher average borrowing levels, resulting from the issuances of new senior notes during 2024. Refer to Note 4 of the Notes to Consolidated Financial Statements for further information related to the Company's debt.

Other income (expense), net was $72.0 in 2024 compared to $29.3 in 2023. The increase was primarily driven by interest income earned on cash and cash equivalents on hand, resulting from increased levels of cash on hand partially driven by the issuance of the new October Senior Notes (defined below) in the fourth quarter of 2024 in anticipation of the Andrew acquisition, which closed on January 31, 2025, along with increased interest rates.

Provision for income taxes was at an effective rate of 18.9% in 2024 and 20.7% in 2023. Provision for income taxes in 2024 included (i) excess tax benefits of $142.6 from stock option exercises, (ii) a discrete tax benefit related to the settlement of tax audits and associated lapses of statutes of limitation, along with a difference in a non-U.S. tax filing position, and (iii) the tax effects related to the aforementioned acquisition-related expenses during the year. Provision for income taxes in 2023 included (i) excess tax benefits of $82.4 from stock option exercises, (ii) the effect of the gain from the bargain purchase acquisition that closed in the second quarter of 2023, and (iii) the tax effects related to acquisition-related expenses during the year. These items incurred in 2024 and 2023 had the aggregate effect of decreasing the effective tax rate and increasing earnings per share by the amounts noted in the table below. Excluding the effect of these items, the Adjusted Effective Tax Rate, a non-GAAP financial measure as defined in the "Non-GAAP Financial Measures" section below within this Item 7, was 24.0% for both 2024 and 2023, as reconciled in the table below to the comparable effective tax rate based on GAAP results. For additional details related to the reconciliation between the U.S. statutory federal tax rate and the Company's effective tax rate for these years, refer to Note 6 of the Notes to Consolidated Financial Statements.

Net income attributable to Amphenol Corporation and Diluted EPS were $2,424.0 and $1.92, respectively, for 2024, compared to $1,928.0 and $1.55, respectively, for 2023. Excluding the effect of the items listed in the table below, Adjusted Net Income attributable to Amphenol Corporation and Adjusted Diluted EPS, non-GAAP financial measures as defined in the "Non-GAAP Financial Measures" section below within this Item 7, were $2,382.1 and $1.89, respectively, for 2024, compared to $1,870.4 and $1.51, respectively, for 2023.

The following table reconciles Adjusted Operating Income, Adjusted Operating Margin, Adjusted Net Income attributable to Amphenol Corporation, Adjusted Effective Tax Rate and Adjusted Diluted EPS (each as defined in the "Non-GAAP Financial Measures" section below) to the most directly comparable U.S. GAAP financial measures for the years ended December 31, 2024 and 2023:

&nbsp;&nbsp;&nbsp;&nbsp;(1) While the terms "operating margin" and "effective tax rate" are not considered U.S. GAAP financial measures, for purposes of this table, we derive the reported (GAAP) measures based on GAAP results, which serve as the basis for the reconciliation to their comparable non-GAAP financial measures.

&nbsp;&nbsp;&nbsp;&nbsp;(2) All percentages and per share amounts in this table were calculated using actual, unrounded results; therefore, the sum of the components may not add due to rounding.

**Liquidity and Capital Resources**

*Liquidity and Cash Requirements*

At December 31, 2025 and 2024, the Company had cash, cash equivalents and short-term investments of $11,434.2 and $3,335.4, respectively. As of December 31, 2025, more than half of the Company's cash, cash equivalents and short-term investments on hand was located in the United States, primarily as a result of the proceeds from the issuance of the November Senior Notes in 2025. As of December 31, 2024, more than half of the Company's cash, cash equivalents and short-term investments on hand was located in the United States, primarily as a result of the proceeds from the issuance of the October Senior Notes in 2024. As of January 9, 2026, the Company used approximately $7,400 of its cash on hand to fund the CommScope acquisition, as discussed elsewhere within this Item 7 and in Note 15 of the accompanying Notes to Consolidated Financial Statements herein. The Company's primary sources of liquidity are internally generated cash provided by operating activities, our cash, cash equivalents and short-term investments on hand, as well as availability under the Commercial Paper Programs, the Revolving Credit Facility and, as of December 31, 2025 but not as of the date of this Annual Report, the Delayed Draw Term Loans (all as defined below). The Company believes that these sources of liquidity, along with access to capital markets (which the Company accessed in 2025 and 2024 for various debt issuances), provide adequate liquidity to meet both its short-term (next 12 months) and reasonably foreseeable long-term requirements and obligations. The Company's debt instruments are defined and discussed in more detail below within this Item 7.

*Cash Requirements from Known Contractual and Other Obligations*

The Company's primary ongoing cash requirements will be for operating and working capital needs, capital expenditures, product development activities, repurchases of our Common Stock, dividends, debt service, taxes due upon the repatriation of foreign earnings (which will be payable upon the repatriation of such earnings), funding of pension obligations, funding of acquisitions, and other contractual obligations and commitments (refer to the table below for the Company's material cash requirements from known contractual and other obligations). The Company has funded all of its recent acquisitions entirely with a combination of cash on hand and net proceeds from its debt instruments, including the Andrew and Trexon acquisitions in 2025 and the CommScope acquisition in 2026, and may fund future acquisitions all or in part with cash. Capital expenditures have historically been in the range of 3% to 4% of net sales. The Company's debt service requirements primarily consist of principal and interest on the Company's Senior Notes, and to the extent of any amounts outstanding, the Revolving Credit Facility, Commercial Paper Programs and Delayed Draw Term Loans (all as defined below). As of December 31, 2025 and 2024, the Company had no borrowings outstanding under the Revolving Credit Facility, Commercial Paper Programs and Delayed Draw Term Loans. However, the Company borrowed $1,534.1 under each of the Delayed Draw Term Loans in January 2026 to fund a portion of the consideration for the CommScope acquisition. In addition, the Company borrowed under the U.S. Commercial Paper Program during 2025 from time to time, the proceeds of which were used for general corporate purposes, including, but not limited to, partially funding the Andrew acquisition, as discussed later within this Item 7. The Company may make additional borrowings under the Revolving Credit Facility and Commercial Paper Programs from time to time in the future.

[**Table of Contents**](#Toc_fix)

The following table summarizes the Company's material short- and long-term cash requirements from known obligations pursuant to certain contracts and commitments as of December 31, 2025, as well as an estimate of the timing in which such obligations and payments are expected to be satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The Company has excluded expected interest payments on the Revolving Credit Facility, Commercial Paper Program and Euro Commercial Paper Program from the above table, as this calculation is largely dependent on average debt levels during each of the years presented. The actual interest payments made related to the Company's Revolving Credit Facility and Commercial Paper Programs in 2025, were approximately $33.7. Expected debt levels, and therefore expected interest payments, are difficult to predict, as they are significantly impacted by items such as future acquisitions, repurchases of Common Stock and dividend payments, as well as payments or additional borrowings that reduce or increase the underlying revolver balance. The table above also excludes borrowings of $1,534.1 under each Delayed Draw Term Loan that occurred subsequent to December 31, 2025 and related interest.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Interest related to the Floating Rate Senior Notes (as defined below) is included in the table above at the effective rate as of December 31, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The Company's operating lease payments included in this table reflect the future minimum undiscounted fixed lease payments, which serve as the basis for calculating the Company's operating lease liabilities as of December 31, 2025. The table above excludes any variable lease payments not included in the measurement of the Company's right-of-use assets and operating lease liabilities, due to their uncertainty. Finance leases are not material to the Company individually or in the aggregate and as such have been excluded from the table above.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Purchase obligations relate primarily to open purchase orders for goods and services, including but not limited to, raw materials and components to be used in production.

&nbsp;&nbsp;&nbsp;&nbsp;(5) This table includes estimated benefit payments expected to be made under the Company's unfunded pension and postretirement benefit plans, as well as the anticipated minimum required contributions under the Company's funded pension plans, the most significant of which covers certain of its U.S. employees. Over the past several years, there has been no minimum requirement for Company contributions to our defined benefit pension plans in the United States ("U.S. Pension Plans") due to prior contributions made in excess of minimum requirements, and as a result, there was no anticipated minimum required contribution included in the table above related to the U.S. Pension Plans for 2026. The Company did not make any voluntary contributions to its U.S. Pension Plans in 2025 and 2024. It is not possible to reasonably estimate expected required contributions in the above table after 2026, since several assumptions are required to calculate minimum required contributions, such as the discount rate and expected returns on pension assets.

&nbsp;&nbsp;&nbsp;&nbsp;(6) As of December 31, 2025, the Company has recorded net liabilities of approximately $311.7 related to unrecognized tax benefits. These liabilities have been excluded from the above table due to the high degree of uncertainty regarding the timing of potential future cash flows. It is difficult to make a reasonably reliable estimate of the amount and period in which all of these liabilities might be paid.

*Repatriation of Foreign Earnings and Related Income Taxes*

The Company has previously indicated an intention to repatriate most of its pre-2025 accumulated earnings and has accrued the foreign and U.S. state and local taxes, if applicable, on those earnings, as appropriate. The associated tax payments are due as the repatriations are made. The Company intends to indefinitely reinvest the remaining pre-2025 foreign earnings. As of December 31, 2025, the Company has accrued the foreign and U.S. state and local taxes associated with the foreign earnings that it intends to repatriate. The Company intends to evaluate future earnings for repatriation, and will accrue for those distributions where appropriate, and to indefinitely reinvest all other foreign earnings. In addition, the Company paid the balance of the Transition Tax (as defined in Note 6 to the accompanying

[**Table of Contents**](#Toc_fix)

Notes to Consolidated Financial Statements), net of applicable tax credits and deductions, during the second quarter of 2025, as permitted under the Tax Cuts and Jobs Act (the "Tax Act").

*H.R. 1*

On July 4, 2025, the United States federal government enacted the tax and spending bill H.R. 1. This legislation contains changes to previously enacted provisions of the Internal Revenue Code and provides for extensions of certain expiring tax provisions included in the Tax Act. Certain corporate tax provisions in H.R. 1 were enacted with retroactive effect to January 1, 2025. H.R. 1 did not have a material impact on our effective tax rate in 2025. The Company continues to evaluate the corporate tax provisions contained within H.R. 1, and the future impact of H.R. 1 depends on several factors, including interpretive regulatory guidance, which has not yet been released.

The following table summarizes the Company's cash flows from operating, investing and financing activities for the years ended December 31, 2025, 2024, and 2023, as reflected in the Consolidated Statements of Cash Flow:

---

| | | | |
|:---|:---|:---|:---|
|  | **Year Ended December 31,**  | **Year Ended December 31,**  | **Year Ended December 31,**  |
|  | **2025** | **2024** | **2023** |
| Net cash provided by operating activities | $5374.7 | $2814.7 | $2528.7 |
| Net cash used in investing activities | (5082.1) | (2648.6) | (1393.7) |
| Net cash provided by (used in) financing activities | 7423.2 | 1729.9 | (1012.4) |
| Effect of exchange rate changes on cash and cash equivalents | 97.8 | (54.0) | (20.7) |
| &nbsp;&nbsp;&nbsp;&nbsp;Net increase in cash and cash equivalents | $7813.6 | $1842.0 | $101.9 |

---

*Operating Activities*

The ability to generate cash from operating activities is one of the Company's fundamental financial strengths. Net cash provided by operating activities ("Operating Cash Flow") was $5,374.7 in 2025, compared to $2,814.7 in 2024 and $2,528.7 in 2023. The increase in Operating Cash Flow in 2025 compared to 2024 is primarily due to the increase in net income and by a lower usage of cash related to the change in working capital, as discussed below. The increase in Operating Cash Flow in 2024 compared to 2023 is primarily due to the increase in net income, partially offset by a higher usage of cash related to the change in working capital, as discussed below.

In 2025, the components of working capital as presented on the accompanying Consolidated Statements of Cash Flow increased $32.3, excluding the impact of acquisitions and foreign currency translation, primarily due to increases in accounts receivable of $964.4, inventories of $487.4 and prepaid expenses and other current assets of $150.7, partially offset by increases in accounts payable of $554.1 and accrued liabilities, including income taxes, of $1,016.1. In 2024, the components of working capital as presented on the accompanying Consolidated Statements of Cash Flow increased $210.5, excluding the impact of acquisitions and foreign currency translation, primarily due to increases in accounts receivable of $586.8, inventories of $200.1 and prepaid expenses and other current assets of $106.8, partially offset by increases in accounts payable of $423.1 and accrued liabilities, including income taxes, of $260.1. In 2023, the components of working capital as presented on the accompanying Consolidated Statements of Cash Flow decreased $149.8, excluding the impact of acquisitions and foreign currency translation, primarily due to decreases in accounts receivable of $146.4 and inventories of $71.4, partially offset by a decrease in accounts payable of $34.6 and an increase in prepaid expenses and other current assets of $34.1.

The following describes the significant changes in the amounts as presented on the accompanying Consolidated Balance Sheets at December 31, 2025 compared to December 31, 2024. Accounts receivable increased $1,429.2 to $4,717.1, primarily driven by higher sales in the fourth quarter of 2025 relative to the fourth quarter of 2024, along with the impact of the five acquisitions (the "2025 Acquisitions") that closed during 2025, and the effect of translation from exchange rate changes ("Translation") at December 31, 2025 compared to December 31, 2024. Days sales outstanding at December 31, 2025 and 2024 were 66 days and 68 days, respectively. Inventories increased $879.2 to $3,424.9, primarily driven by the impact of the 2025 Acquisitions, along with the impact of higher sales in 2025 relative to the prior year and Translation. Inventory days at December 31, 2025 and 2024 were 77 days and 80 days, respectively. Prepaid expenses and other current assets increased $174.0 to $691.0, primarily due to increases in various prepaid expenses and other current receivables, along with the impact of the 2025 Acquisitions. Property, plant and equipment, net, increased $593.8 to $2,305.6, primarily due to purchases of $1,040.3 and the impact of the 2025 Acquisitions and Translation, partially offset by depreciation of $640.1. Goodwill increased $2,339.2 to $10,575.4, primarily driven by goodwill recognized from the 2025 Acquisitions, in particular the Andrew and Trexon acquisitions, and Translation.

[**Table of Contents**](#Toc_fix)

Other intangible assets, net, increased $1,016.3 to $2,241.4, primarily due to the recognition of certain intangible assets related to the 2025 Acquisitions, in particular the Andrew and Trexon acquisitions, partially offset by amortization of $192.0 associated with the Company's current intangible assets. Other long-term assets increased $266.2 to $847.3, primarily due to an increase in operating lease right-of-use assets resulting from both new and renewed lease agreements entered into during 2025 and acquired leases resulting from acquisitions. Accounts payable increased $842.5 to $2,661.9, primarily due to increased purchasing activity related to the higher sales levels in 2025, along with the impact of the 2025 Acquisitions and Translation. Payable days at December 31, 2025 and 2024 were 60 days and 58 days, respectively. Total accrued expenses, including accrued income taxes, increased $1,341.0 to $3,203.7, primarily as a result of increases in accrued salaries, wages and employee benefits, accrued income taxes, and various other accrued expenses, along with the impact of the 2025 Acquisitions. Accrued pension and postretirement benefit obligations increased $8.4 to $138.2, primarily due to the impact of lower discount rates used to calculate our projected benefit obligation and the funded status of our defined benefit pension plans. Other long-term liabilities, including deferred tax liabilities, increased $335.3 to $1,221.4, primarily as a result of an increase in long-term lease liabilities resulting from both new and renewed lease agreements entered into during 2025, along with acquired leases resulting from acquisitions.

In addition to Operating Cash Flow, the Company also considers Free Cash Flow, a non-GAAP financial measure defined in the "Non-GAAP Financial Measures" section below, as a key metric in measuring the Company's ability to generate cash. The following table reconciles Free Cash Flow to its most directly comparable U.S. GAAP financial measure for the years ended December 31, 2025, 2024 and 2023. The increase in Free Cash Flow in 2025 compared to 2024 was driven by the increase in Operating Cash Flow, partially offset by the increased capital expenditures levels, as described above. Free Cash Flow decreased modestly in 2024 compared to 2023, as the increase in capital expenditures was largely offset by the increase in Operating Cash Flow, as described above.

| Proceeds from disposals of property, plant and equipment (GAAP) | 14.8 | 7.8 | 4.0 |
| Free Cash Flow (non-GAAP) | $4392.9 | $2157.1 | $2159.9 |

---

*Investing Activities*

Cash flows from investing activities primarily consist of cash flows associated with capital expenditures, proceeds from disposals of property, plant and equipment, net, purchases (sales and maturities) of short- and long-term investments, and acquisitions.

Net cash used in investing activities was $5,082.1 in 2025, compared to $2,648.6 in 2024 and $1,393.7 in 2023. In 2025, net cash used in investing activities was primarily driven by the use of $3,818.6 to fund acquisitions, capital expenditures (net of disposals) of $981.8 and net purchases of short-term investments of $281.7. In 2024, net cash used in investing activities was primarily driven by the use of $2,156.4 to fund acquisitions and capital expenditures (net of disposals) of $657.6, partially offset by net sales and maturities of short-term investments of $163.5. In 2023, net cash used in investing activities was primarily driven by the use of $970.4 to fund acquisitions, capital expenditures (net of disposals) of $368.8, and net purchases of short-term investments of $59.4. The elevated capital expenditures in 2025 were driven by investments, primarily in support of the robust growth in our IT datacom market. We currently expect this elevated level of capital spending to continue into 2026 to support the continued growth we are experiencing related to AI applications in our IT datacom market.

*Financing Activities*

Cash flows from financing activities primarily consist of cash flows associated with borrowings and repayments of the Company's credit facilities and other long-term debt, repurchases of Common Stock, proceeds from stock option exercises, dividend payments, and distributions to and purchases of noncontrolling interests.

Net cash provided by financing activities was $7,423.2 in 2025 and $1,729.9 in 2024, compared to net cash used in financing activities of $1,012.4 in 2023. In 2025, net cash provided by financing activities was primarily driven by (i) net cash proceeds from borrowings of $8,921.7, primarily related to the issuances of the 2028 Senior Notes, the 2032 Euro Notes and the November Senior Notes (each as defined below), and (ii) cash proceeds of $553.0 from the exercise of stock options, partially offset by (a) redemption of the 2.050% Senior Notes of $400.0, (b) repurchases of the

[**Table of Contents**](#Toc_fix)

Company's Common Stock of $665.2, (c) dividend payments of $802.2, (d) payments of $89.1 related to debt financing costs associated with the Delayed Draw Term Loans, as well as the issuances of the 2028 Senior Notes, the 2032 Euro Notes and the November Senior Notes, (e) settlement of the treasury locks of $88.0, and (f) distributions to and purchases of noncontrolling interests of $5.8. In 2024, net cash provided by financing activities was primarily driven by (i) net cash proceeds from borrowings of $2,991.3, primarily related to the issuances of the April Senior Notes and October Senior Notes, each as defined below, and (ii) cash proceeds of $447.4 from the exercise of stock options, partially offset by (a) repurchases of the Company's Common Stock of $689.3, (b) dividend payments of $595.1, (c) debt repayments of $364.4, primarily related to the redemption of the 3.20% Senior Notes in the second quarter of 2024, (d) distributions to and purchases of noncontrolling interests of $33.0, and (e) payments of $28.4 related to debt financing costs associated with the Company's amended and restated revolving credit facility in March 2024 as well as the issuances of the April Senior Notes and October Senior Notes.

The Company has significant flexibility to meet its financial commitments. The Company uses debt financing to lower the overall cost of capital and increase return on stockholders' equity. The Company's debt financing includes the use of the Commercial Paper Programs, the Revolving Credit Facility, and senior notes as part of its overall cash management strategy.

On March 21, 2024, the Company entered into a third amended and restated credit agreement, which amended and restated its $2,500.0 unsecured revolving credit facility, increasing the lenders' aggregate unsecured revolving commitments under the facility by $500.0 to $3,000.0 (the "Revolving Credit Facility"). The Revolving Credit Facility matures in March 2029 and gives the Company and certain of its subsidiaries the ability to borrow, in various currencies, at a spread that varies, based on the Company's debt rating, over certain currency-specific benchmark rates, which benchmark rates, in the case of U.S. dollar borrowings, are either the base rate or the adjusted term Secured Overnight Financing Rate ("SOFR"). The Revolving Credit Facility was undrawn on the date it was amended and restated. The Company may utilize the Revolving Credit Facility for general corporate purposes. As of December 31, 2025 and 2024, there were no outstanding borrowings under the Revolving Credit Facility. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants. On December 31, 2025, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

On August 22, 2025, the Company entered into (i) a three-year, $2,000.0 unsecured delayed draw term loan credit agreement among the Company, certain subsidiaries of the Company, a syndicate of financial institutions, and JPMorgan Chase Bank, N.A., acting as the administrative agent (the "Three-Year Delayed Draw Term Loan"), which is scheduled to mature on the three-year anniversary of the funding date, and (ii) a 364-day, $2,000.0 unsecured delayed draw term loan credit agreement among the Company, certain subsidiaries of the Company, a syndicate of financial institutions and JPMorgan Chase Bank, N.A., acting as the administrative agent (the "364-Day Delayed Draw Term Loan" and, together with the Three-Year Delayed Draw Term Loan, the "Delayed Draw Term Loans", and individually, a "Delayed Draw Term Loan"), which is scheduled to mature on the date that is 364 days after the funding date. Each Delayed Draw Term Loan may only be drawn in a single drawing over the life of the applicable facility. Each Delayed Draw Term Loan may be repaid at any time without premium or penalty and, once repaid, cannot be reborrowed. Interest rates under each Delayed Draw Term Loan are based on a spread over either the base rate or the adjusted term SOFR, which spread varies based on the Company's debt rating. On November 13, 2025, the aggregate commitment amount in respect of each of the Delayed Draw Term Loans was individually reduced to $1,534.1. As of December 31, 2025, the Company had not yet drawn upon either Delayed Draw Term Loan, and as such, there were no outstanding borrowings under either Delayed Draw Term Loan. On December 31, 2025, the Company was in compliance with the financial covenants under each Delayed Draw Term Loan. In January 2026, the Company drew the full $1,534.1 available under each of the Delayed Draw Term Loans to fund a portion of the consideration for the CommScope acquisition, which closed on January 9, 2026, as discussed further in Note 15 of the accompanying Notes to Consolidated Financial Statements.

The Company has a commercial paper program (the "U.S. Commercial Paper Program") pursuant to which the Company may issue short-term unsecured commercial paper notes (the "USCP Notes" or "U.S. Commercial Paper") in one or more private placements in the United States. On March 21, 2024, in conjunction with the increase in the capacity of the Revolving Credit Facility, the Company increased the borrowings available under its U.S. Commercial Paper Program by $500.0. As of December 31, 2025, the maximum aggregate principal amount outstanding of USCP Notes at any time is $3,000.0. The Company utilizes borrowings under the U.S. Commercial Paper Program for general corporate purposes, which, in recent years, have included fully or partially funding acquisitions, as well as repaying certain outstanding senior notes. The Company borrowed under the U.S. Commercial Paper Program throughout much of 2025 and 2024, the proceeds of which were used for general corporate purposes, including, but not limited to, partially funding the Andrew and CIT acquisitions. Before December 31, 2025 and 2024, the Company repaid all of its USCP Notes then outstanding. As of December 31, 2025 and 2024, there were no USCP Notes outstanding.

The Company and one of its wholly owned European subsidiaries (the "Euro Issuer") also have a commercial paper program (the "Euro Commercial Paper Program" and, together with the U.S. Commercial Paper Program, the "Commercial Paper Programs"), pursuant to which the Euro Issuer may issue short-term unsecured commercial paper notes (the "ECP Notes" and, together with the USCP Notes, the "Commercial Paper"), which are guaranteed by the Company and are to be issued outside of the United States. The ECP Notes may be issued in Euros, Sterling, U.S. dollars or other currencies. The maximum aggregate principal amount outstanding of ECP Notes at any time is $2,000.0. The Company utilizes borrowings under the Euro Commercial Paper Program for general corporate purposes, which may include, for example, fully or partially funding acquisitions. The Company did not borrow under the Euro Commercial Paper Program during 2025 or 2024. As of December 31, 2025 and 2024, there were no ECP Notes outstanding.

[**Table of Contents**](#Toc_fix)

Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the Revolving Credit Facility, as of December 31, 2025, the authorization from the Board limits the maximum aggregate principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper or similar programs, along with outstanding amounts under the Revolving Credit Facility, at any time to $3,000.0. The Commercial Paper Programs are rated A-2 by Standard & Poor's and P-2 by Moody's and, based on the Board's authorization described above, are currently backstopped by the Revolving Credit Facility, as amounts undrawn under the Revolving Credit Facility are available to repay Commercial Paper, if necessary. The Company reviews its optimal mix of short-term and long-term debt regularly and may replace certain amounts of Commercial Paper, short-term debt and current maturities of long-term debt with new issuances of long-term debt in the future.

As of December 31, 2025, the Company has outstanding senior notes (the "Senior Notes") as follows:

On January 9, 2026, the Company used the net proceeds from the November Senior Notes, together with borrowings under the Delayed Draw Term Loans and cash on hand, to fund the cash consideration for the CommScope acquisition, along with fees and expenses related thereto.

The Euro Issuer has two outstanding unsecured senior notes issued in Europe (the "Existing Euro Notes", together with the 2032 Euro Notes, the "Euro Notes" and, together with the U.S. Senior Notes, the "Senior Notes"). The Euro Issuer has €500.0 (approximately $545.4 at date of issuance) aggregate principal amount of unsecured 0.750% Senior Notes due May 4, 2026 (the "2026 Euro Notes"), the net proceeds of which were used to repay amounts outstanding under the then existing revolving credit facility. In addition, the Euro Issuer also has €500.0 (approximately $574.6 at date of issuance) aggregate principal amount of unsecured 2.000% Senior Notes due October 8, 2028 (the "2028 Euro Notes"), the net proceeds of which were used to repay a portion of the outstanding amounts under our Commercial Paper Programs, with the remainder of the net proceeds being used for general corporate purposes.

The Senior Notes impose certain obligations on the Company and prohibit various actions by the Company unless it satisfies certain financial requirements. On December 31, 2025, the Company was in compliance with all requirements under its Senior Notes. Refer to Note 4 of the Notes to Consolidated Financial Statements for further information related to the Company's debt.

On April 23, 2024, the Board authorized a new stock repurchase program under which the Company may purchase up to $2,000.0 of its Common Stock during the three-year period ending on the close of business on April 28, 2027 (the "2024 Stock Repurchase Program"). The 2024 Stock Repurchase Program became effective on April 29, 2024. During the year ended December 31, 2025, the Company repurchased 7.4 million shares of its Common Stock for $665.2 under the 2024 Stock Repurchase Program. Of the total repurchases made in 2025 under the 2024 Stock Repurchase Program, 6.0 million shares, or $512.3, have been retired by the Company, with the remainder of the repurchased shares retained in Treasury stock at the time of repurchase. From January 1, 2026 to January 31, 2026, the Company repurchased 0.3 million additional shares of its Common Stock for $44.2, and, as of February 1, 2026, the Company has remaining authorization to purchase up to $826.9 of its Common Stock under the 2024 Stock Repurchase Program. The timing and amount of any future repurchases 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.

In April 2021, the Board authorized a stock repurchase program under which the Company could purchase up to $2,000.0 of its Common Stock during the three-year period ending April 27, 2024 (the "2021 Stock Repurchase Program"). During the year ended December 31, 2024, the Company repurchased 4.1 million shares of its Common Stock for $225.6 under the 2021 Stock Repurchase Program. All of the repurchased shares under the 2021 Stock Repurchase Program during 2024 have been retired by the Company. As a result of these repurchases, the Company completed all repurchases authorized under the 2021 Stock Repurchase Program, and, therefore, the 2021 Stock Repurchase Program has terminated.

Contingent upon declaration by the Board, the Company pays a quarterly dividend on shares of its Common Stock.

**Pensions**

The Company and certain of its subsidiaries in the United States have defined benefit pension plans ("U.S. Pension Plans"), which cover certain U.S. employees and which represent the majority of the plan assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Pension Plans' benefits are generally based on years of service and compensation and are generally noncontributory. The majority of U.S. employees are not covered by the U.S. Pension Plans and are instead covered by various defined contribution plans. The Company also has an unfunded Supplemental Employee Retirement Plan ("SERP" and, together with the U.S. Pension Plans, "U.S. Plans"), which provides for the payment of the portion of annual pension that cannot be paid from the retirement plan as a result of regulatory limitations on average compensation for purposes of the benefit computation. Certain foreign subsidiaries also have defined benefit plans covering their employees (the "Foreign Plans" and, together with the U.S. Plans, the "Plans"). The total liability for accrued pension and postretirement benefit obligations associated with the Company's pension and postretirement benefit plans decreased in 2025 to $87.5 from $89.2 in 2024, primarily driven by the effect of lower discount rates in 2025 on our projected benefit obligations along with actual positive returns on plan assets in 2025, partially offset by interest cost. There is no current requirement for cash contributions to any of the U.S. Plans, and the Company plans to evaluate annually, based on actuarial calculations and the investment performance of the Plans' assets, the timing and amount of cash contributions in the future, if any.

Refer to Note 9 of the Notes to Consolidated Financial Statements for further discussion of the Company's benefit plans and other postretirement benefit plans.

**Acquisitions**

During 2025, the Company completed five acquisitions (the "2025 Acquisitions"), including the acquisitions of Andrew and Trexon, for approximately $3,818.6, net of cash acquired. The Andrew acquisition has been included in the Communications Solutions segment, three acquisitions including Trexon have been included in the Harsh Environment Solutions segment, and one acquisition has been included in the Interconnect and Sensor Systems segment. The 2025 Acquisitions were each funded using cash on hand, proceeds from the October Senior Notes, borrowings under the U.S. Commercial Paper Program, or a combination thereof. The 2025 Acquisitions were not material, either individually or in the aggregate, to the Company's financial results.

During 2024, the Company completed two acquisitions (the "2024 Acquisitions"), including the acquisition of CIT, for approximately $2,156.4, net of cash acquired. Both acquisitions have been included in the Harsh Environment Solutions segment. The 2024 Acquisitions were each funded using cash on hand, proceeds from the April Senior Notes or borrowings under the U.S. Commercial Paper Program, or a combination thereof. The 2024 Acquisitions are not material, either individually or in the aggregate, to the Company's financial results.

*Acquisition-related Expenses*

In 2025, the Company incurred $181.2 ($148.8 after-tax) of acquisition-related expenses, comprised primarily of (i) the non-cash amortization related to the value associated with acquired backlog resulting from the Andrew and Trexon acquisitions and external transaction costs related to acquisitions (such acquisition-related expenses aggregating $103.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $77.8 associated with the Andrew acquisition (such costs are recorded in Cost of sales in the Consolidated Statements of Income).

[**Table of Contents**](#Toc_fix)

In 2024, the Company incurred $145.6 ($119.3 after-tax) of acquisition-related expenses, comprised primarily of (i) external transaction costs associated with acquisitions and the non-cash amortization related to the value associated with acquired backlog resulting from the CIT acquisition (such acquisition-related expenses aggregating $127.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the Consolidated Statements of Income).

*Acquisition of CommScope* 

On January 9, 2026, pursuant to a purchase agreement announced on August 4, 2025, the Company completed the acquisition of the Connectivity and Cable Solutions Business (which we now refer to collectively as "CommScope") from Vistance Networks, Inc. ("Vistance", formerly known as CommScope Holding Company, Inc.) for an aggregate purchase price of approximately $10,500.0 in cash, subject to customary post-closing adjustments. The Company funded the CommScope acquisition through a combination of net proceeds from the Delayed Draw Term Loans, the November Senior Notes and cash on hand, as discussed in Note 4 of the accompanying Notes to Consolidated Financial Statements.

For further discussion of the Company's acquisitions, refer to Note 11 and Note 15 of the Notes to Consolidated Financial Statements.

**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.

**Inflation and Costs**

The cost of the Company's products is influenced by the cost of a wide variety of raw materials. The Company strives to offset the impact of increases in the cost of raw materials, labor and services through price increases, productivity improvements and cost saving programs. However, in certain markets, implementing price increases can be difficult, and there is no guarantee that the Company will be successful. From time to time, the Company has encountered, and in the future may encounter, difficulties in obtaining certain raw materials or components necessary for production at reasonable costs due to supply chain constraints and logistical challenges, which may include regulatory restrictions and the imposition of additional tariffs. 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 increased commodity prices 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. For a discussion of certain risks related to inflation and costs, refer to the risk factor titled "*The Company and certain of its suppliers and customers have experienced, and may in the future experience, difficulties obtaining certain raw materials and components, and the cost of certain of the Company's raw materials and components may increase*" in Part I, Item 1A. *Risk Factors* herein.

**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 currency devaluations. Changes in exchange rates can positively or negatively affect the Company's sales, operating margins and equity. The Company attempts to mitigate currency risk in a number of ways, 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. However, there can be no assurance that any or all such actions taken by the Company will be fully effective in successfully managing currency risk, including in the event of a significant and sudden decline in the value of any of the foreign currencies of the Company's worldwide operations. For further discussion of foreign exchange exposures, risks and uncertainties, refer to the risk factor titled "*The Company's results can be positively or negatively affected by changes in foreign currency exchange rates*" in Part I, Item 1A. *Risk Factors* herein.

**Non-GAAP Financial Measures**

In addition to assessing the Company's financial condition, results of operations, liquidity and cash flows in accordance with U.S. GAAP, management utilizes certain non-GAAP financial measures, defined below, as part of its internal reviews for purposes of monitoring, evaluating and forecasting the Company's financial performance, communicating operating results to the Board and assessing related employee compensation measures. Management believes that these non-GAAP financial measures may be helpful to investors in assessing the Company's overall financial performance, trends and year-over-year comparative results, in addition to the reasons noted below. Non-GAAP financial measures related to operating income, operating margin, net income attributable to Amphenol Corporation, effective tax rate and diluted EPS exclude income and expenses that are not directly related to the Company's operating performance during the years presented. Items excluded in the presentation of such non-GAAP financial measures in any period may consist of, without limitation, acquisition-related expenses, refinancing-related costs, gains associated with bargain purchase acquisitions, the excess tax benefits related to stock-based compensation and certain other discrete tax items including, but not limited to, (i) the impact of tax audits relating to prior periods and (ii) significant changes in tax law. Non-GAAP financial measures related to net sales exclude the impact of foreign currency exchange rates and acquisitions. The non-GAAP financial information contained herein is included for supplemental purposes only and should not be considered in isolation or as a substitute for or superior to the related U.S. GAAP financial measures. In addition, these non-GAAP financial measures are not necessarily the same or comparable to similar measures presented by other companies as such measures may be calculated differently or may exclude different items.

The non-GAAP financial measures defined below should be read in conjunction with the Company's financial statements presented in accordance with U.S. GAAP. The reconciliations of these non-GAAP financial measures to the most directly comparable U.S. GAAP financial measures for the years ended December 31, 2025, 2024 and 2023 are included in "Results of Operations" and "Liquidity and Capital Resources" within this Item 7:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Adjusted Diluted EPS* is defined as diluted earnings per share (as reported in accordance with U.S. GAAP), excluding income and expenses and their specific tax effects that are not directly related to the Company's operating performance during the years presented. Adjusted Diluted EPS is calculated as Adjusted Net Income attributable to Amphenol Corporation, as defined below, divided by the weighted average outstanding diluted shares as reported in the Consolidated Statements of Income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Adjusted Effective Tax Rate* is defined as Provision for income taxes, as reported in the Consolidated Statements of Income, expressed as a percentage of Income before income taxes, as reported in the Consolidated Statements of Income, each excluding income and expenses and their specific tax effects that are not directly related to the Company's operating performance during the years presented.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Adjusted Net Income attributable to Amphenol Corporation* is defined as Net income attributable to Amphenol Corporation, as reported in the Consolidated Statements of Income, excluding income and expenses and their specific tax effects that are not directly related to the Company's operating performance during the years presented.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Adjusted Operating Income* is defined as Operating income, as reported in the Consolidated Statements of Income, excluding income and expenses that are not directly related to the Company's operating performance during the years presented.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Adjusted Operating Margin* is defined as Adjusted Operating Income (as defined above) expressed as a percentage of Net sales (as reported in the Consolidated Statements of Income).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Constant Currency Net Sales Growth* is defined as the year-over-year percentage change in net sales growth, excluding the impact of changes in foreign currency exchange rates. The Company's results are subject to volatility related to foreign currency translation fluctuations. As such, management evaluates the Company's sales performance based on actual sales growth in U.S. dollars, as well as Organic Net Sales Growth (as defined below) and Constant Currency Net Sales Growth, and believes that such information is useful to investors to assess the underlying sales trends.

[**Table of Contents**](#Toc_fix)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Free Cash Flow* is defined as (i) Net cash provided by operating activities ("Operating Cash Flow" - as reported in accordance with U.S. GAAP) less (ii) capital expenditures (as reported in accordance with U.S. GAAP), net of proceeds from disposals of property, plant and equipment (as reported in accordance with U.S. GAAP), all of which are derived from the Consolidated Statements of Cash Flow. Free Cash Flow is an important liquidity measure for the Company, as we believe it is useful for management and investors to assess our ability to generate cash, as well as to assess how much cash can be used to reinvest in the growth of the Company or to return to stockholders through either stock repurchases or dividends.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Organic Net Sales Growth* is defined as the year-over-year percentage change in net sales growth resulting from operating volume and pricing changes and excludes the impact of (i) changes in foreign currency exchange rates (described above), which is outside the control of the Company, and (ii) acquisitions, both of which are taken as a percentage of the respective prior year period(s) net sales. The acquisition impact 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(s) and/or prior comparable year(s) presented. Such net sales related to these acquisitions do not reflect the underlying growth of the Company on a comparative basis. Management evaluates the Company's sales performance based on actual sales growth in U.S. dollars, as well as Constant Currency Net Sales Growth (as defined above) and Organic Net Sales Growth, and believes that such information is useful to investors to assess the underlying sales trends.

**Recent Accounting Pronouncements**

Refer to Note 1 of the Notes to Consolidated Financial Statements for a discussion of recently issued accounting pronouncements, including those adopted by the Company.

**Critical Accounting Estimates**

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on historical experience along with other assumptions that we believe are reasonable in formulating our bases for making judgements regarding the carrying amounts of assets and liabilities that are not readily apparent elsewhere. Estimates are adjusted as new information becomes available. Actual results could differ from those estimates. The Company believes that the following accounting policies and estimates are most critical since they require significant assumptions and judgments that inherently are subject to risks and uncertainties. The significant accounting policies are more fully described in Note 1 of the Notes to Consolidated Financial Statements.

***Revenue Recognition***

The Company's primary source of revenues consist of product sales to either end customers and their appointed contract manufacturers (including original equipment manufacturers) or to distributors. Our revenues are derived from contracts with customers, which in most cases are customer purchase orders that may be governed by master sales agreements. For each contract, the promise to transfer the control of the products, each of which is individually distinct, is considered to be the identified performance obligation. As part of the consideration promised in each contract, the Company evaluates the customer's credit risk. Our contracts do not have any significant financing components, as payment terms are generally due net 30 to 120 days after delivery. Although products are almost always sold at fixed prices, in determining the transaction price, we evaluate whether the price is subject to refund (due to returns) or adjustment (due to volume discounts, rebates, or price concessions) to determine the net consideration we expect to be entitled to. We allocate the transaction price to each distinct product based on its relative standalone selling price. Taxes assessed by governmental authorities and collected from the customer, including but not limited to sales and use taxes and value-added taxes, are not included in the transaction price.

[**Table of Contents**](#Toc_fix)

The vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer, which generally occurs when we ship or deliver the product from our manufacturing facility to our customers, when our customer accepts and has legal title of the goods, and where the Company has a present right to payment for such goods. Based on the respective contract terms, most of our contracts' revenues are recognized either (i) upon shipment based on free on board ("FOB") shipping point or (ii) when the product arrives at its destination. For the years ended December 31, 2025, 2024 and 2023, less than 5% of our net sales were recognized over time, where the associated contracts relate to the sale of goods with no alternative use as they are only sold to a single customer and whose underlying contract terms provide the Company with an enforceable right to payment, including a reasonable profit margin, for performance completed to date, in the event of customer termination. For the contracts recognized over time, we typically record revenue using the input method, based on the materials and labor costs incurred to date relative to the contract's total estimated costs. This method reasonably depicts when and as control of the goods transfers to the customer, since it measures our progress in producing the goods which is generally commensurate with this transfer of control. Since we typically invoice our customers at the same time that we satisfy our performance obligations, contract assets and contract liabilities related to our contracts with customers recorded in the Consolidated Balance Sheets were not material as of December 31, 2025 and 2024.

Standard product warranty coverage, which provides assurance that our products will conform to the contractually agreed-upon specifications for a limited period from the date of shipment, is typically offered, while extended or separately priced warranty coverage is typically not offered. The warranty claim is generally limited to a credit equal to the purchase price or a promise to repair or replace the product for a specified period of time at no additional charge. We estimate our warranty liability based on historical experience, product history, and current trends.

***Income Taxes***

Deferred income taxes are provided for revenue and expenses which are recognized in different periods for income tax and financial statement reporting purposes. The Company recognizes the effects of changes in tax laws and rates on deferred income taxes in the period in which legislation is enacted. Deferred income taxes are provided on undistributed earnings of foreign subsidiaries in the period in which the Company determines it no longer intends to permanently reinvest such earnings outside the United States. As of December 31, 2025, the Company has not provided for deferred income taxes on undistributed foreign earnings of approximately $1,750 related to certain geographies, as it is the Company's intention to permanently reinvest such earnings outside the United States. It is impracticable to calculate the amount of taxes that would be payable if these undistributed foreign earnings were to be repatriated. In addition, the Company remains indefinitely reinvested with respect to its financial statement basis in excess of tax basis of its investments in foreign subsidiaries. It is not practicable to determine the deferred tax liability with respect to such basis differences. Deferred tax assets are regularly assessed for recoverability based on both historical and anticipated earnings levels and a valuation allowance is recorded when it is more likely than not that these amounts will not be recovered.

The tax effects of an uncertain tax position taken or expected to be taken in income tax returns are recognized only if it is "more likely than not" to be sustained on examination by the taxing authorities, based on its technical merits as of the reporting date. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company includes estimated interest and penalties related to unrecognized tax benefits in the provision for income taxes.

As a result of the Tax Act, the global intangible low-taxed income ("GILTI") provision imposed a tax on certain earnings of foreign subsidiaries. The Company elected an accounting policy to account for GILTI as a period cost. The U.S. Treasury Department has issued final interpretive guidance relating to certain provisions of the Tax Act and proposed additional guidance related to the same provisions. The Company will account for the impact of additional guidance in the period in which any new guidance is released, if appropriate.

**Item 7A. Quantitative and Qualitative Disclosures About Market Risk**

*(amounts in millions)*

The Company, in the normal course of doing business, is exposed to a variety of risks, including market risks associated with foreign currency exchange rates and changes in interest rates. The Company does not have any significant concentration with any one counterparty.

[**Table of Contents**](#Toc_fix)

***Foreign Currency Exchange Rate Risk***

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. Changes in exchange rates can positively or negatively affect the Company's sales, operating margins and equity. The Company attempts to mitigate currency risk in a number of ways, 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. However, there can be no assurance that any or all such actions taken by the Company will be fully effective in successfully managing currency risk, including in the event of a significant and sudden decline in the value of any of the foreign currencies of the Company's worldwide operations.

One of the Company's wholly owned European subsidiaries (the "Euro Issuer") has two outstanding unsecured senior notes issued in Europe (collectively, the "Existing Euro Notes"), each of which was issued with a principal amount of €500.0. The 0.750% Euro Senior Notes, which were issued in May 2020, mature on May 4, 2026, while the 2.000% Euro Senior Notes, which were issued in October 2018, mature on October 8, 2028. Additionally, on June 16, 2025, the Company issued €600.0 aggregate principal amount of unsecured 3.125% Senior Notes due June 16, 2032 (the "2032 Euro Notes", and, together with the Existing Euro Notes, the "Euro Notes"). The Company and the Euro Issuer also have a commercial paper program (the "Euro Commercial Paper Program" and, together with the U.S. Commercial Paper Program, the "Commercial Paper Programs"), pursuant to which the Euro Issuer may issue, outside of the United States, short-term unsecured commercial paper notes. In addition to the Euro Notes, which are denominated in Euros, the Company may borrow, from time to time, under the Company's $3,000.0 unsecured revolving credit facility (the "Revolving Credit Facility") and Euro Commercial Paper Program, and such borrowings have been and may continue to be denominated in various foreign currencies, including the Euro. When borrowing in foreign currencies, there can be no assurance that the Company can successfully manage changes in exchange rates, including in the event of a significant and sudden decline in the value of any of the foreign currencies in which such borrowings are made. Refer to Note 4 of the Notes to Consolidated Financial Statements for a discussion of the Company's debt.

The Company also utilizes foreign exchange forward contracts to hedge foreign currency exchange rate fluctuations for exposures associated with (i) certain transactions denominated in foreign currencies and (ii) net investments in certain foreign subsidiaries from which we expect to repatriate earnings to the United States. As of December 31, 2025, the fair value of such foreign exchange forward contracts was not material. A 10% change in foreign currency exchange rates would not have a material effect on the value of the hedges as of December 31, 2025 and 2024. The Company does not engage in purchasing forward contracts for trading or speculative purposes, and our derivative financial instruments are with large financial institutions with strong credit ratings. As of December 31, 2025, the Company does not have any significant concentration of exposure with any one counterparty. Refer to Note 1 and Note 5 of the accompanying Notes to Consolidated Financial Statements for a discussion of derivative financial instruments.

***Interest Rate Risk***

The Company is subject to market risk from exposure to changes in interest rates based on the Company's financing activities. The Company attempts to manage its exposure to interest rate risk through a mix of fixed and variable rate debt and hedging contracts in some cases. The Company currently has various fixed rate senior notes outstanding, in both the United States and Europe, with various maturity dates, the most recent of which were issued in 2025. In August 2025, the Company entered into $1,500.0 10-year and $1,000.0 30-year notional treasury lock derivative instruments to hedge interest rate risk prior to the issuance of the November Senior Notes. In November 2025, the Company issued the November Senior Notes. The treasury locks were settled upon the issuance of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively, for a cumulative loss of $88.0 ($67.4 after-tax). The cumulative after-tax loss was recorded in Accumulated other comprehensive income (loss) and is being amortized to Interest expense over the terms of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively. Refer to Note 4 and Note 5 of the accompanying Notes to Consolidated Financial Statements herein for further discussion related to these debt instruments.

[**Table of Contents**](#Toc_fix)

Any borrowings under the Revolving Credit Facility bear interest at rates that fluctuate with a spread that varies, based on the Company's debt rating, over certain currency-specific benchmark rates, which benchmark rates in the case of U.S. dollar borrowings are either the base rate or the adjusted term Secured Overnight Financing Rate ("SOFR"). Any borrowings under the Commercial Paper Programs are subject to floating interest rates. Borrowings under each Delayed Draw Term Loan bear interest at rates that fluctuate with a spread over either the base rate or the adjusted term SOFR, which spread varies based on the Company's debt rating. The Floating Rate Senior Notes bear interest at a floating rate per annum, reset quarterly, equal to compounded SOFR, plus 0.53%. Therefore, when the Company borrows under these debt instruments, the Company is exposed to market risk related to changes in interest rates. As of December 31, 2025 and 2024, the Company had no borrowings outstanding under the Revolving Credit Facility, Commercial Paper Programs and Delayed Draw Term Loans. However, the Company borrowed $1,534.1 under each of the Delayed Draw Term Loans in January 2026 to fund a portion of the consideration for the CommScope acquisition. In addition, the Company borrowed under the U.S. Commercial Paper Program during 2025 from time to time, the proceeds of which were used for general corporate purposes, including, but not limited to, partially funding the Andrew acquisition in January 2025, as discussed further in Note 11 of the Notes to Consolidated Financial Statements. Although all such borrowings were repaid before the end of 2025, the Company may make additional borrowings under the Revolving Credit Facility and the Commercial Paper Programs from time to time in the future. As of December 31, 2025, 3% of the Company's outstanding borrowings were subject to floating interest rates. Outstanding borrowings subject to floating interest rates will be higher going forward as a result of the borrowings under the Delayed Draw Term Loans that occurred subsequent to December 31, 2025, as discussed above.

To the extent that interest rates change and the Company has outstanding borrowings under any of our floating rate debt instruments (Commercial Paper Programs, Revolving Credit Facility and Delayed Draw Term Loans), our interest expense and interest payments will be impacted accordingly. A 10% change in the interest rate at December 31, 2025 and 2024 under our Revolving Credit Facility, Commercial Paper Programs, Delayed Draw Term Loans or Floating Rate Senior Notes would not have a material effect on interest expense. Although the Company does not expect changes in interest rates to have a material effect on net income or cash flows in 2026, there can be no assurance that interest rates will not change significantly from current levels.

**Item 8. Financial Statements and Supplementary Data**

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the stockholders and the Board of Directors of Amphenol Corporation

**Opinions on the Financial Statements and Internal Control over Financial Reporting**

We have audited the accompanying consolidated balance sheets of Amphenol Corporation and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in equity, and cash flow, for each of the three years in the period ended December 31, 2025, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control — Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America (generally accepted accounting principles). Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control — Integrated Framework (2013)* issued by COSO.

**Basis for Opinions**

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

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

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

**Definition and Limitations of Internal Control over Financial Reporting** 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

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

**Critical Audit Matter**

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

**Income Taxes — Unrecognized Tax Benefits — Refer to Notes 1 and 6 to the financial statements**

**Critical Audit Matter Description**

The Company operates in the U.S. and numerous foreign taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by tax authorities and may not be fully sustained, despite the Company's belief that the underlying tax positions are fully supportable. The tax effects of an uncertain tax position taken or expected to be taken in income tax returns are recognized only if it is "more likely than not" to be sustained on examination by the taxing authorities, based on its technical merits as of the reporting date. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement.

Management judgment is required to identify and evaluate each unrecognized tax benefit to determine whether the more likely than not recognition threshold has been met. Further, the evaluation of each unrecognized tax benefit requires management to apply specialized skill and knowledge related to the identified position. The Company has unrecognized tax benefits of $316.5 million, including penalties and interest, as of December 31, 2025.

**How the Critical Audit Matter Was Addressed in the Audit**

Our audit procedures related to uncertain tax positions included the following, among others:

● We tested the effectiveness of controls over the unrecognized tax benefits for income taxes, including management's controls over the identification of uncertain tax positions, determination of whether it is more likely than not that the tax positions will be sustained, and recording of unrecognized tax benefits.

● With the assistance of our income tax specialists, we evaluated management's significant judgements regarding unrecognized tax benefits including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Assessing the reasonableness of the methods and processes used by management to identify uncertain tax positions including but not limited to:

◾ Evaluating former and ongoing tax audits and notices by tax authorities

◾ Evaluating transactions for which third-party tax advice or tax opinions were received

◾ Determining if there is any relevant additional information available that was not identified and considered in management's assessment

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Assessing the technical merits of a sample of positions identified and the reasonableness of the methodology used to determine the unrecognized tax benefit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Evaluating management's conclusion with respect to whether a sample of unrecognized tax benefits accounted for in prior periods have been effectively settled and/or whether the statute of limitations has expired and, if so, whether the resolution of the tax position has been appropriately accounted for in the financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Evaluating a sample of tax positions that have not yet settled or are within statute to determine whether any new information regarding the sustainability of these tax positions or measurement of tax benefit is present and has been appropriately accounted for in the financial statements.

**AMPHENOL CORPORATION**

**Notes to Consolidated Financial Statements**

*(All amounts included in the following Notes to Consolidated Financial Statements are presented in millions, except share and per share data, unless otherwise noted)*

***Note 1—Summary of Significant Accounting Policies***

All segment information throughout the Consolidated Financial Statements and Notes to Consolidated Financial Statements is presented in accordance with the three reportable business segments. Refer to Note 13 herein for further details related to the Company's reportable business segments.

***Use of Estimates***

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP" or "GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company's management evaluates these significant estimates and assumptions that affect the consolidated financial statements and related disclosures. Estimates used in calculating certain accounts, including but not limited to, the allowance for doubtful accounts, provisions for slow-moving or obsolete inventory, revenue recognition, income taxes and related valuation allowances, goodwill and intangible assets from acquisitions, and pensions, are developed based on historical experience or other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.

[**Table of Contents**](#Toc_fix)

***Principles of Consolidation***

The consolidated financial statements are prepared in U.S. dollars and include the accounts of the Company and its wholly owned and majority-owned subsidiaries. Intercompany account balances and transactions have been eliminated in consolidation. The results of companies acquired are included in the Consolidated Financial Statements from the effective date of acquisition. The Company's results of operations for each of the three years ended December 31, 2025 may not necessarily be indicative of its future operating results. The accompanying Financial Statements and Notes herein reflect all adjustments, including normal recurring adjustments considered necessary for a fair presentation of the results, in conformity with U.S. GAAP.

***Cash and Cash Equivalents***

Cash and cash equivalents consist of cash and liquid investments with an original maturity of three months or less. The carrying amounts approximate fair values of those instruments, the majority of which are typically in non-U.S. bank accounts. However, as of December 31, 2025, more than half of the Company's cash and cash equivalents on hand was located in the United States, primarily as a result of the proceeds from the issuance of the November Senior Notes, as discussed in more detail in Note 4 herein.

***Short-term and Long-term Investments***

Short-term investments primarily consist of certificates of deposit with original or remaining maturities of 12 months or less. Long-term investments primarily consist of certificates of deposit with original and remaining maturities of more than 12 months. The carrying amounts of these short-term and long-term investments approximate their respective fair values, the vast majority of which are in non-U.S. bank accounts. Short-term investments are presented separately as its own line item on the Consolidated Balance Sheets. Long-term investments are recorded in Other long-term assets on the Consolidated Balance Sheets.

***Accounts Receivable***

Accounts receivable is stated at net realizable value. The Company regularly reviews accounts receivable balances and adjusts the receivable reserves as necessary whenever events or circumstances indicate the carrying value may not be recoverable. The Company assesses and records an allowance for expected credit losses on accounts receivable.

***Inventories***

Inventories are stated at the lower of cost or net realizable value. The principal components of cost included in inventories are materials, direct labor and manufacturing overhead. The Company regularly reviews inventory quantities on hand, evaluates the realizability of inventories and adjusts the carrying value as necessary based on forecasted product demand. Provisions for slow-moving and obsolete inventory are made based on historical experience and product demand.

***Depreciable Assets***

Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the respective asset lives determined on a composite basis by asset group or on a specific item basis using the estimated useful lives of such assets, which generally range from 3 to 12 years for machinery and equipment and office equipment and 20 to 40 years for buildings. Leasehold building improvements are amortized over the shorter of the remaining lease term or estimated useful life of such improvements. The Company periodically reviews fixed asset lives. Depreciation expense is included in both Cost of sales and Selling, general and administrative expenses in the Consolidated Statements of Income, dependent upon the specific categorization and use of the underlying asset being depreciated. The Company assesses the impairment of property, plant and equipment subject to depreciation, whenever events or changes in circumstances indicate the carrying value may not be recoverable. Factors the Company considers important, which could trigger an impairment review, include significant changes in the manner of the use of the asset, significant changes in historical trends in operating performance, significant changes in projected operating performance, and significant negative economic trends. There have been no impairments recorded in 2025, 2024 or 2023 as a result of such reviews.

[**Table of Contents**](#Toc_fix)

Purchases of property, plant and equipment were $1,040.3 and $665.4 for the years ended December 31, 2025 and 2024, respectively. Capital expenditures, which includes both purchases of property, plant and equipment and amounts included in Accounts payable, for the years ended December 31, 2025 and 2024, primarily related to investments in manufacturing capabilities, both in the U.S. and internationally. Capital expenditures included in Accounts payable were $207.0 and $163.3 as of December 31, 2025 and 2024, respectively, which primarily related to these investments.

***Leases***

Amphenol is a lessee of buildings, office space, automobiles and equipment throughout the world, nearly all of which are classified as operating leases expiring at various dates. The Company determines if an arrangement qualifies as a lease at lease inception. Lease right-of-use ("ROU") assets and lease liabilities for existing operating leases are recognized on the Consolidated Balance Sheets. Operating lease liabilities are recorded based on the present value of the future lease payments over the lease term, assessed as of the commencement date. The Company's real estate leases, which are comprised primarily of manufacturing facilities, warehouses and sales offices, represent the vast majority of our operating lease liabilities and generally have a lease term between 2 and 12 years. The remaining leases primarily consist of machinery and equipment used in production, office equipment and vehicles, each with various lease terms. The vast majority of our leases are comprised of fixed lease payments, with a small percentage of the Company's real estate leases including lease payments tied to a rate or index which may be subject to variability. Certain real estate leases also include executory costs such as common area maintenance (non-lease component), as well as property insurance and property taxes (non-components). We account for the lease and non-lease components as a single lease component for our real estate leases. Lease payments, which may include lease components, non-lease components and non-components, are included in the measurement of the Company's lease liabilities to the extent that such payments are either fixed amounts or variable amounts based on a rate or index (fixed in substance) as stipulated in the lease contract. Any actual costs in excess of such amounts are expensed as incurred as variable lease cost.

Substantially all of our lease agreements do not specify an implicit borrowing rate, and as such, the Company utilizes its incremental borrowing rate by lease term, in order to calculate the present value of our future lease payments. The discount rate represents a risk-adjusted rate on a secured basis, and is the rate at which the Company would borrow funds to satisfy the scheduled lease liability payment streams commensurate with the lease term. For new or renewed leases, the discount rate is determined using available data at lease commencement and based on the lease term including any reasonably certain renewal periods.

Some of our lease agreements, primarily related to real estate, include options for the Company to either renew (extend) or early terminate the lease. Leases with renewal options allow the Company to extend the lease term typically between 1 and 6 years. Renewal options are reviewed at lease commencement to determine if such options are reasonably certain of being exercised, which could impact the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, or specific characteristics unique to the particular lease that would make it reasonably certain that we would exercise such option. In most cases and unless there is an economic, financial or business reason to do so, the Company has concluded that renewal and early termination options are not reasonably certain of being exercised by the Company (and thus not included in our ROU asset and lease liability).

Refer to Note 10 herein for further information related to our lease portfolio.

***Goodwill***

Goodwill represents the excess purchase cost over the fair value of net assets acquired in business combinations. The Company performs its evaluation for the impairment of goodwill associated with the Company's reporting units on an annual basis as of each July 1, or more frequently if an event occurs or circumstances change that would indicate that a reporting unit's carrying amount may be impaired. The Company reviews its reporting unit structure each year, or more frequently based on changes in our organization. The Company continues to define its reporting units as the three reportable business segments.

[**Table of Contents**](#Toc_fix)

Annually, the Company performs its goodwill impairment assessment on its three reporting units. In the third quarter of 2025, as part of its annual evaluations, the Company performed a quantitative goodwill impairment assessment for each reporting unit. As part of the quantitative assessment, the Company estimated the fair value of each of its reporting units using an equal weighting of the market and income approaches, which the Company believes provide the best indicators of their fair value. The market approach utilizes market prices and other relevant metrics for comparable publicly-traded companies with similar operating and investment characteristics, as well as recent transactions of similar businesses within the industry, while the income approach is based on estimate discounted future cash flows. Significant estimates and assumptions were used in the Company's goodwill impairment assessment, including both historical and projected revenue and profitability data, the determination and selection of appropriate publicly-traded market comparison companies, and the calculation of comparable earnings-based and other multiples derived from comparable publicly-traded companies and from recent transactions within the industry. As part of its quantitative approach, the Company evaluated whether there were reasonably likely changes to management's estimates and assumptions that would have a material impact on the results of the goodwill impairment assessment. In the third quarter of 2024, as part of our annual evaluations, the Company utilized the option to first assess qualitative factors to determine whether it was necessary to perform the quantitative goodwill impairment assessment. As part of these assessments, the Company reviews qualitative factors, which include, but are not limited to, economic, market and industry conditions, as well as the financial performance of each reporting unit. In accordance with applicable guidance, an entity is not required to calculate the fair value of a reporting unit if, after assessing these qualitative factors, the Company determines that it is more likely than not that the fair value of each of its reporting units is greater than its respective carrying amount. As of July 1, 2025 and 2024, the Company determined that it was more likely than not that the fair value of each of its reporting units was substantially in excess of their respective carrying amounts and, therefore, no goodwill impairment resulted from the assessments as of July 1, 2025 and 2024.

The Company has not recognized any goodwill impairment in 2025, 2024 or 2023 in connection with its annual impairment assessments. Refer to Note 12 herein for further details related to the carrying amount of goodwill by segment.

***Intangible Assets***

Other than goodwill, intangible assets primarily consist of customer relationships, proprietary technology, acquired backlog and license agreements and are generally amortized over the estimated periods of benefit. The fair value associated with acquired identifiable intangible assets are generally valued based on discounted cash flow analyses, independent appraisals and certain estimates made by management. The Company assesses and reviews its identifiable intangible assets, subject to amortization, for potential impairment whenever events or changes in circumstances indicate the intangible asset's carrying amount may not be recoverable. Factors the Company considers important, which could trigger an impairment review, include significant changes in the manner of the use of the asset, changes in historical trends in operating performance, significant changes in projected operating performance, anticipated future cash flows and significant negative economic trends. Any indefinite-lived intangible assets that are not subject to amortization, which are comprised of certain trade names, are reviewed at least annually for impairment. In the third quarter of 2025, the Company performed its annual assessment of these identifiable indefinite-lived intangible assets. Based on its assessment, the Company determined that it was more likely than not that the fair value of the indefinite-lived intangible assets exceeded their respective carrying amounts. There has been no impairment associated with the Company's intangible assets in 2025, 2024 or 2023 as a result of such reviews.

***Acquisitions***

The Company accounts for acquisitions using the acquisition method of accounting, which requires that assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. The purchase price of acquisitions is allocated to the tangible and identifiable intangible assets acquired and liabilities and noncontrolling interests assumed based on estimated fair values, and any excess purchase price over the identifiable assets acquired and liabilities assumed is recorded as goodwill. Any subsequent adjustments to the purchase price allocation prior to the completion of the measurement period will be reflected as an adjustment to goodwill in the period in which the adjustments are identified. The Company may use independent valuation specialists to assist in determining the estimated fair values of assets acquired and liabilities assumed, which could require certain significant management assumptions and estimates.

***Revenue Recognition***

The Company recognizes revenue upon the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services. The vast majority of our sales are recognized when products are shipped from our facilities or delivered to our customers, depending on the respective contractual terms. A nominal portion of our contracts have revenue recognized over time as control of the goods transfers, rather than when the goods are delivered, and title, risk and reward of ownership are passed to the customer, since they have no alternative use and for which the Company has an enforceable right to payment, including a reasonable profit margin, from the customer for performance completed to date. Refer to Note 13 herein for further discussion regarding the Company's disaggregation of net sales.

The Company's primary source of revenues consist of product sales to either end customers and their appointed contract manufacturers (including original equipment manufacturers) or to distributors, and the vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer. Revenues are derived from contracts with customers, which in most cases are customer purchase orders that may be governed by master sales agreements. For each contract, the promise to transfer the control of the products, each of which is individually distinct, is considered to be the identified performance obligation. As part of the consideration promised in each contract, the Company evaluates the customer's credit risk. Our contracts do not have any significant financing components, as payment terms are generally due net 30 to 120 days after delivery. Although products are almost always sold at fixed prices, in determining the transaction price, we evaluate whether the price is subject to refund (due to returns) or adjustment (due to volume discounts, rebates, or price concessions) to determine the net consideration we expect to be entitled to. We allocate the transaction price to each distinct product based on its relative standalone selling price. Taxes assessed by governmental authorities and collected from the customer, including but not limited to sales and use taxes and value-added taxes, are not included in the transaction price.

The vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer. With limited exceptions, the Company recognizes revenue at the point in time when we ship or deliver the product from our manufacturing facility to our customer, when our customer accepts and has legal title of the goods, and where the Company has a present right to payment for such goods. Based on the respective contract terms, most of our contracts' revenues are recognized either (i) upon shipment based on free on board ("FOB") shipping point or (ii) when the product arrives at its destination. For the years ended December 31, 2025, 2024 and 2023, less than 5% of our net sales were recognized over time, where the associated contracts relate to the sale of goods with no alternative use as they are only sold to a single customer and whose underlying contract terms provide the Company with an enforceable right to payment, including a reasonable profit margin, for performance completed to date, in the event of customer termination. For the contracts recognized over time, we typically record revenue using the input method, based on the materials and labor costs incurred to date relative to the contract's total estimated costs. This method reasonably depicts when and as control of the goods transfers to the customer, since it measures our progress in producing the goods, which is generally commensurate with this transfer of control. Since we typically invoice our customers at the same time that we satisfy our performance obligations, contract assets and contract liabilities related to our contracts with customers recorded in the Consolidated Balance Sheets were not material as of December 31, 2025 and 2024.

The Company receives customer orders negotiated with multiple delivery dates that may extend across more than one reporting period until the contract is fulfilled, the end of the order period is reached, or a pre-determined maximum order value has been reached. Orders typically fluctuate from quarter to quarter based on customer demand and general business conditions. It is generally expected that a substantial portion of our remaining performance obligations will be fulfilled within three months. Nearly all of our performance obligations are fulfilled within one year. Since our performance obligations are part of contracts that generally have original durations of one year or less, we have not disclosed the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied performance obligations as of December 31, 2025 and 2024.

*Sales to Distributors and Resellers*

Sales to certain distributors and resellers are made under terms allowing certain price adjustments and limited rights of return of the Company's products held in their inventory or upon sale to their end customers. The Company maintains a reserve for unprocessed and estimated future price adjustment claims and returns as a refund liability. The reserve is recorded as a reduction to revenue in the same period that the related revenue is recorded and is calculated based on an analysis of historical claims and returns over a period of time to appropriately account for current pricing and business trends. Similarly, sales returns and allowances are recorded based on historical return rates, as a reduction to revenue with a corresponding reduction to cost of sales for the estimated cost of inventory that is expected to be returned. These reserves were not material to the Consolidated Balance Sheets as of December 31, 2025 and 2024.

*Warranty*

Standard product warranty coverage, which provides assurance that our products will conform to the contractually agreed-upon specifications for a limited period from the date of shipment, is typically offered, while extended or separately priced warranty coverage is typically not offered. The warranty claim is generally limited to a credit equal to the purchase price or a promise to repair or replace the product for a specified period of time at no additional charge. We estimate our warranty liability based on historical experience, product history, and current trends, and record warranty expense in Cost of sales in the Consolidated Statements of Income. Warranty liabilities and related warranty expense have not been and were not material in the accompanying Consolidated Financial Statements as of and for the years ended December 31, 2025, 2024 and 2023.

*Shipping and Handling Costs*

The Company accounts for shipping and handling activities related to contracts with customers as a cost to fulfill our promise to transfer control of the related product, including any such costs incurred after the customer has obtained control of the goods. Shipping and handling costs are generally charged to and paid by the majority of our customers as part of the contract. For a nominal portion of our customer contracts, primarily for certain customers in the communications networks market (a market primarily in the Communications Solutions segment), such costs are not separately charged to the customers. Shipping and handling costs are included in Cost of sales in the accompanying Consolidated Statements of Income.

*Contract Assets and Contract Liabilities*

The Company records contract assets or contract liabilities depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Contract assets represent unbilled receivables, which generally arise when revenue recognized over time exceed amounts billed to customers. Contract liabilities represent billings or advanced consideration received from customers in excess of revenue recognized to date. As the Company's performance obligations are typically less than one year, these amounts are generally recorded as current in the accompanying Consolidated Balance Sheets within Prepaid expenses and other current assets or Other accrued expenses as of December 31, 2025 and 2024. Contract assets and contract liabilities recorded in the Consolidated Balance Sheets were not material as of December 31, 2025 and 2024.

*Contract Costs*

The Company's policy is to capitalize any incremental costs incurred to obtain a customer contract, only to the extent that such costs are explicitly chargeable to the customer and the benefit associated with the costs is expected to be longer than one year. Otherwise, such costs are expensed as incurred and recorded within Selling, general and administrative expenses in the accompanying Consolidated Statements of Income. Incremental costs to fulfill customer orders, which are mostly comprised of pre-production and set-up costs, are generally capitalized to the extent such costs are contractually guaranteed to be reimbursed by the customer. Otherwise, such costs are expensed as incurred. Capitalized contract costs to obtain a contract or to fulfill a contract that are not accounted for under other existing accounting standards are recorded as either other current or long-term assets on the accompanying Consolidated Balance Sheets, depending on the timing of when the Company expects to recognize the expense, and are generally amortized consistent with the timing of when transfer of control of the related goods occurs. Such capitalized contract costs were not material as of December 31, 2025 and 2024, and the related amortization expense was not material for the years ended December 31, 2025, 2024 and 2023.

***Retirement Pension Plans***

Costs for retirement pension plans include current service costs and amortization of prior service costs over the average working life expectancy. It is the Company's policy to fund current pension costs taking into consideration minimum funding requirements and maximum tax deductible limitations. The expense of retiree medical benefit programs is recognized during the employees' service with the Company. The recognition of expense and the related obligation for retirement pension plans and medical benefit programs is significantly impacted by estimates and assumptions made by management such as discount rates used to value certain liabilities, expected return on assets, mortality projections and future health care costs. The Company uses third-party specialists such as actuaries and investment advisors to assist management in appropriately measuring the expense and obligations associated with pension and other postretirement plan benefits.

***Stock-Based Compensation***

The Company accounts for its stock option, restricted share and phantom stock awards based on the fair value of the award at the date of grant and recognizes compensation expense over the service period that the awards are expected to vest. The Company recognizes expense for stock-based compensation with graded vesting on a straight-line basis over the vesting period of the entire award. Stock-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ or are expected to differ from such estimates. Changes in estimated forfeitures are recognized in the period of change and impact the amount of expense to be recognized in future periods. The expense incurred for stock-based compensation plans is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Income.

***Income Taxes***

Deferred income taxes are provided for revenue and expenses which are recognized in different periods for income tax and financial statement reporting purposes. The Company recognizes the effects of changes in tax laws and rates on deferred income taxes in the period in which legislation is enacted. Deferred income taxes are provided on undistributed earnings of foreign subsidiaries in the period in which the Company determines it no longer intends to permanently reinvest such earnings outside the United States. As of December 31, 2025, the Company has not provided for deferred income taxes on undistributed foreign earnings of approximately $1,750 related to certain geographies, as it is the Company's intention to permanently reinvest such earnings outside the United States. It is impracticable to calculate the amount of taxes that would be payable if these undistributed foreign earnings were to be repatriated. In addition, the Company remains indefinitely reinvested with respect to its financial statement basis in excess of tax basis of its investments in foreign subsidiaries. It is not practicable to determine the deferred tax liability with respect to such basis differences. Deferred tax assets are regularly assessed for recoverability based on both historical and anticipated earnings levels and a valuation allowance is recorded when it is more likely than not that these amounts will not be recovered.

The tax effects of an uncertain tax position taken or expected to be taken in income tax returns are recognized only if it is "more likely than not" to be sustained on examination by the taxing authorities, based on its technical merits as of the reporting date. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company includes estimated interest and penalties related to unrecognized tax benefits in the provision for income taxes.

As a result of the U.S. Tax Cuts and Jobs Act of 2017 (the "Tax Act"), the global intangible low-taxed income ("GILTI") provision imposed a tax on certain earnings of foreign subsidiaries. The Company elected an accounting policy to account for GILTI as a period cost. The U.S. Treasury Department has issued final interpretive guidance relating to certain provisions of the Tax Act and proposed additional guidance related to the same provisions. The Company will account for the impact of additional guidance in the period in which any new guidance is released, if appropriate.

***Foreign Currency Translation***

The financial position and results of operations of the Company's foreign subsidiaries are measured, in most cases, using local currency as the functional currency. Assets and liabilities of such subsidiaries have been translated into U.S. dollars at current exchange rates and related revenues and expenses have been translated at weighted average exchange rates. The aggregate effect of translation adjustments is included as a component of Accumulated other comprehensive income (loss) within equity. Transaction gains and losses related to operating assets and liabilities are included in Cost of sales in the accompanying Consolidated Statements of Income.

***Research and Development***

Costs incurred in connection with the development of new products and applications are expensed as incurred. Research and development expenses for the creation of new and improved products and processes were $647.0, $453.0 and $342.2 for the years ended December 31, 2025, 2024 and 2023, respectively, and are included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Income.

***Environmental Obligations***

The Company recognizes the potential cost for environmental remediation activities when site assessments are made, remediation efforts are probable and related amounts can be reasonably estimated. The Company assesses its environmental liabilities as necessary and appropriate through regular reviews of contractual commitments, site assessments, feasibility studies and formal remedial design and action plans.

***Net Income per Common Share***

Basic earnings per common share is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of common shares outstanding. Diluted earnings per common share is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of outstanding common shares, including dilutive common shares, the dilutive effect of which relates to stock options. Diluted earnings per common share assumes the exercise of outstanding dilutive stock options using the treasury stock method. Refer to Note 8 of the Notes to Consolidated Financial Statements for a reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding, used in the calculation of earnings per share (basic and diluted) for Amphenol Corporation.

***Treasury Stock***

Treasury stock purchases are recorded at cost. Any issuances from treasury shares are recorded using the weighted average cost method.

***Noncontrolling Interests***

The Company presents equity attributable to noncontrolling interests in consolidated entities as its own caption within equity, separate from the Company's equity attributable to Amphenol Corporation stockholders, to the extent that such noncontrolling interests do not have redemption features that would otherwise result in such noncontrolling interests being considered redeemable, as discussed below. Net income attributable to noncontrolling interests is classified below net income. Earnings per share is determined after the impact of the noncontrolling interests' share in net income of the Company.

[**Table of Contents**](#Toc_fix)

***Redeemable Noncontrolling Interests***

The Company reports noncontrolling interests in the mezzanine ("temporary equity") section, between liabilities and equity, of the Consolidated Balance Sheets, to the extent that such noncontrolling interests have redemption features, such as a put option, that is redeemable at a fixed or determinable price on a fixed or determinable date at the option of the holder, or upon the occurrence of an event that is not solely within the control of the Company. Due to its redeemable features that are outside the control of the Company, the redeemable noncontrolling interest is and will continue to be reported in the mezzanine section in the Consolidated Balance Sheets for as long as the put option is exercisable by the option holder. The carrying amount of the redeemable noncontrolling interest, initially valued at fair value as part of acquisition accounting, is adjusted each reporting period to equal the greater of the (i) redemption value or (ii) carrying value of the noncontrolling interest, adjusted each reporting period for income or loss attributable to the noncontrolling interest and any distributions made to date. The redemption value is generally calculated based on a multiple of earnings. Any measurement adjustments, if applicable, to the redeemable noncontrolling interest are recognized in Additional paid-in capital in the Consolidated Balance Sheets. Net income attributable to redeemable noncontrolling interests is classified below net income. Earnings per share is determined after the impact of the redeemable noncontrolling interests' share in net income of the Company. Refer to Note 5 herein for further details related to the redeemable noncontrolling interests.

***Derivative Financial Instruments***

The Company records each of its derivatives at fair value within the accompanying Consolidated Balance Sheets, and the respective accounting treatment for each derivative is based on its hedge designation. We do not enter into derivative financial instruments for trading or speculative purposes, and our derivative financial instruments are with large financial institutions with strong credit ratings. As of December 31, 2025, the Company does not have any significant concentration of exposure with any one counterparty. Refer to Note 5 herein for further discussion of our derivative financial instruments.

*Cash Flow Hedges*

From time to time, the Company utilizes derivative financial instruments in the management of interest rate and foreign currency exposures. Such cash flow hedges include foreign exchange forward contracts to hedge exposure to foreign currency exchange rate fluctuations for certain transactions denominated in foreign currencies. As of December 31, 2025 and 2024, there were no outstanding cash flow hedge contracts. Gains and losses on derivatives designated as cash flow hedges resulting from changes in fair value are recorded in Accumulated other comprehensive income (loss), and subsequently reflected in Cost of sales in the Consolidated Statements of Income in a manner that matches the timing of the actual income or expense of such instruments with that of the hedged transaction. Any ineffective portion of the change in the fair value of designated hedging instruments is included in the Consolidated Statements of Income. Cash flows associated with cash flow hedges are classified and reported consistent with the cash flows associated with the underlying hedged item.

The Company has used treasury lock derivative instruments to hedge the exposure to changes in benchmark interest rates associated with forecasted issuances of fixed-rate debt. In August 2025, the Company entered into $1,500.0 10-year and $1,000.0 30-year notional treasury lock derivative instruments, which were settled upon the issuance of the November Senior Notes as discussed in Note 5 herein. As of December 31, 2025, there were no outstanding treasury lock derivative instruments. Gains and losses on the effective portion of treasury lock derivative instruments resulting from changes in fair value are recorded in Accumulated other comprehensive income (loss) and amortized to Interest expense over the term of the related debt upon issuance. Any ineffective portion is recognized immediately in interest expense. Cash flows associated with treasury locks are classified and reported within financing activities in the Consolidated Statements of Cash Flow.

[**Table of Contents**](#Toc_fix)

*Net Investment Hedges*

The Company is exposed to variability in the U.S. dollar equivalent of the net investments in our foreign subsidiaries and, by extension, the U.S. dollar equivalent of any foreign earnings repatriated to the U.S. due to potential changes in foreign currency exchange rates. As a result, from time to time, the Company enters into foreign exchange forward contracts to hedge the net investments in certain foreign subsidiaries from which we expect to repatriate earnings to the United States. As of December 31, 2025 and 2024, there were no outstanding net investment hedge contracts, and, as such, the aggregate notional value of our outstanding net investment hedge contracts was nil. However, in June 2025, the Company issued the 2032 Euro Notes as discussed in Note 4 herein, which have been designated as a hedge of the Company's net investment in certain foreign subsidiaries. For such instruments that are designated and qualify as a net investment hedge, the effective portion of the hedging instrument's gain or loss is reported as a component of other comprehensive income (loss) and recorded in Accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. The gain or loss will be subsequently reclassified into net earnings if the net investment in the hedged foreign operation is either sold or substantially liquidated. Cash flows associated with net investment hedges are classified and reported within investing activities in the Consolidated Statements of Cash Flow. Cash flows associated with net investment hedges were not material for the years ended December 31, 2025, 2024 and 2023.

*Non-Designated Derivatives*

The Company enters into certain derivative financial instruments, from time to time, that are not designated as hedging instruments. The Company enters into such foreign exchange forward contracts to reduce and minimize the impact of foreign currency fluctuations arising from the change in fair value of certain foreign currency denominated assets and liabilities. These non-designated derivative instruments are adjusted to fair value each period through earnings, within the financial statement line item to which the derivative instrument relates. For each of the three years ended December 31, 2025, such non-designated derivative instruments, including their impact to the Consolidated Statements of Income, were not material to the Company. Cash flows associated with non-designated hedges are classified and reported consistent with the cash flows associated with the underlying hedged item.

***Recent Accounting Pronouncements***

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures* ("ASU 2023-09"). The intent of ASU 2023-09 is to improve the disclosures around a company's rate reconciliation information and certain types of income taxes companies are required to pay. Specifically, these new disclosure requirements provide more transparency regarding income taxes companies pay in the United States and other countries, along with more disclosure around a company's rate reconciliation, among other new disclosure requirements, such that users of financial statements can get better information about how the operations, related tax risks, tax planning and operational opportunities of companies affect their effective tax rates and future cash flow prospects. ASU 2023-09 is effective for annual fiscal years beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments under ASU 2023-09 should be applied on a prospective basis, although retrospective application is permitted. As part of this Annual Report, the Company adopted ASU 2023-09, which was applied prospectively. Refer to Note 6 herein for further details regarding this adoption.

In November 2024, the FASB issued ASU No. 2024-03, *Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses* ("ASU 2024-03"). The intent of ASU 2024-03 is to improve financial statement disclosures regarding information about certain costs and expenses. Specifically, ASU 2024-03 requires the disaggregation of significant expenses within the income statement expense line items, including, but not limited to, purchases of inventory, employee compensation, depreciation, intangible asset amortization, and selling expenses, among others, as well as a qualitative description of the remaining amounts not separately disaggregated quantitatively. ASU 2024-03 is effective for annual fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments under ASU 2024-03 should be applied on a prospective basis, although retrospective application is permitted. The Company is currently evaluating the potential impact of ASU 2024-03 on its consolidated financial statements and disclosures.

[**Table of Contents**](#Toc_fix)

In December 2025, the FASB issued ASU No. 2025-11, *Interim Reporting (Topic 270): Narrow-Scope Improvements* ("ASU 2025-11"), which clarifies the applicability of the interim reporting guidance, the types of interim reporting, and the form and content of interim financial statements in accordance with U.S. GAAP. Per the FASB, the amendment does not intend to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements but rather provide clarity and improve navigability of the existing interim reporting requirements. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. The amendments under ASU 2025-11 should be applied on a prospective basis, although retrospective application is permitted. The Company is currently evaluating the potential impact of ASU 2025-11 on its interim consolidated financial statements and disclosures.

***Delayed Draw Term Loans***

On August 22, 2025, the Company entered into (i) a three-year, $2,000.0 unsecured delayed draw term loan credit agreement among the Company, certain subsidiaries of the Company, a syndicate of financial institutions and JPMorgan Chase Bank, N.A., acting as the administrative agent (the "Three-Year Delayed Draw Term Loan"), which is scheduled to mature on the three-year anniversary of the funding date, and (ii) a 364-day, $2,000.0 unsecured delayed draw term loan credit agreement among the Company, certain subsidiaries of the Company, a syndicate of financial institutions and JPMorgan Chase Bank, N.A., acting as the administrative agent (the "364-Day Delayed Draw Term Loan" and, together with the Three-Year Delayed Draw Term Loan, the "Delayed Draw Term Loans," and individually, a "Delayed Draw Term Loan"), which is scheduled to mature on the date that is 364 days after the funding date. Each Delayed Draw Term Loan may only be drawn in a single drawing over the life of the applicable facility. Each Delayed Draw Term Loan may be repaid at any time without premium or penalty and, once repaid, cannot be reborrowed. Interest rates under each Delayed Draw Term Loan are based on a spread over either the base rate or the adjusted term SOFR, which spread varies based on the Company's debt rating. The carrying value of any borrowings under each Delayed Draw Term Loan would approximate their fair value, primarily due to its market interest rates, and would be classified as Level 2 in the fair value hierarchy (Note 5). On November 13, 2025, the aggregate commitment amount in respect of each of the Delayed Draw Term Loans was individually reduced to $1,534.1. As of December 31, 2025, the Company had not yet drawn upon either Delayed Draw Term Loan. However, in January 2026, the Company drew the full $1,534.1 available under each of the Delayed Draw Term Loans to fund a portion of the consideration for the acquisition of CommScope's Connectivity and Cable Solutions Business ("CommScope"), which closed on January 9, 2026, as discussed further in Note 15 herein. In accordance with the credit agreements, the borrowings under the 364-Day Delayed Draw Term Loan and the 3-Year Delayed Draw Term Loan will mature on January 8, 2027 and January 9, 2029, respectively. Interest rates on each Delayed Draw Term Loan were based on a spread over the adjusted term SOFR based on the Company's debt rating, and on the borrowing date, the effective interest rates were approximately 4.42% and 4.55% for the 364-Day Delayed Draw Term Loan and the Three-Year Delayed Draw Term Loan, respectively. The Delayed Draw Term Loans required payment of certain commitment fees prior to the funding thereunder and require that the Company satisfy certain financial covenants, which financial covenants are the same as those under the Revolving Credit Facility. On December 31, 2025, the Company was in compliance with the financial covenants under each Delayed Draw Term Loan. During the year ended December 31, 2025, the Company incurred $20.1 of debt financing costs associated with the issuance of the Delayed Draw Term Loans.

***Revolving Credit Facility***

On March 21, 2024, the Company entered into a third amended and restated credit agreement, which amended and restated its $2,500.0 unsecured revolving credit facility, increasing the lenders' aggregate unsecured revolving commitments under the facility by $500.0 to $3,000.0 (the "Revolving Credit Facility"). The Revolving Credit Facility matures in March 2029 and gives the Company and certain of its subsidiaries the ability to borrow, in various currencies, at a spread that varies, based on the Company's debt rating, over certain currency-specific benchmark rates, which benchmark rates, in the case of U.S. dollar borrowings, are either the base rate or the adjusted term Secured Overnight Financing Rate ("SOFR"). The Revolving Credit Facility was undrawn on the date it was amended and restated. The Company may utilize the Revolving Credit Facility for general corporate purposes. As of December 31, 2025 and 2024, there were no outstanding borrowings under the Revolving Credit Facility. The carrying value of any borrowings under the Revolving Credit Facility would approximate their fair value, primarily due to their market interest rates, and would be classified as Level 2 in the fair value hierarchy (Note 5). Any outstanding borrowings under the Revolving Credit Facility are classified as long-term debt in the accompanying Consolidated Balance Sheets. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants.

***Commercial Paper Programs***

The Company has a commercial paper program (the "U.S. Commercial Paper Program") pursuant to which the Company may issue short-term unsecured commercial paper notes (the "USCP Notes" or "U.S. Commercial Paper") in one or more private placements in the United States. The maturities of the USCP Notes vary but may not exceed 397 days from the date of issue. The USCP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom, and bear varying interest rates on a fixed or floating basis. On March 21, 2024, in conjunction with the increase in the capacity of the Revolving Credit Facility, the Company increased the borrowings

[**Table of Contents**](#Toc_fix)

available under its U.S. Commercial Paper Program by $500.0. As of December 31, 2025, the maximum aggregate principal amount outstanding of USCP Notes at any time is $3,000.0. The Company utilizes borrowings under the U.S. Commercial Paper Program for general corporate purposes, which, in recent years, have included fully or partially funding acquisitions, as well as repaying certain outstanding senior notes. The Company borrowed under the U.S. Commercial Paper Program throughout much of 2025 and 2024, the proceeds of which were used for general corporate purposes, including, but not limited to, partially funding the acquisitions of Andrew in January 2025 and CIT in May 2024, as discussed further in Note 11 herein. Before the end of the fourth quarter of 2025 and 2024, the Company repaid all of its USCP Notes then outstanding. As of December 31, 2025 and 2024, there were no USCP Notes outstanding.

The Company and one of its wholly owned European subsidiaries (the "Euro Issuer") also have a commercial paper program (the "Euro Commercial Paper Program" and, together with the U.S. Commercial Paper Program, the "Commercial Paper Programs"), pursuant to which the Euro Issuer may issue short-term unsecured commercial paper notes (the "ECP Notes" and, together with the USCP Notes, the "Commercial Paper"), which are guaranteed by the Company and are to be issued outside of the United States. The maturities of the ECP Notes will vary but may not exceed 183 days from the date of issue. The ECP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom or a premium thereto and bear varying interest rates on a fixed or floating basis. The ECP Notes may be issued in Euros, Sterling, U.S. dollars or other currencies. The maximum aggregate principal amount outstanding of ECP Notes at any time is $2,000.0. The Company utilizes borrowings under the Euro Commercial Paper Program for general corporate purposes, which may include, for example, fully or partially funding acquisitions. The Company did not borrow under the Euro Commercial Paper Program during 2025 or 2024. As of December 31, 2025 and 2024, there were no ECP Notes outstanding.

Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the Revolving Credit Facility, as of December 31, 2025, the authorization from the Board limits the maximum aggregate principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper or similar programs, along with outstanding amounts under the Revolving Credit Facility, at any time to $3,000.0. The Commercial Paper Programs are rated A-2 by Standard & Poor's and P-2 by Moody's and, based on the Board's authorization described above, are currently backstopped by the Revolving Credit Facility, as amounts undrawn under the Revolving Credit Facility are available to repay Commercial Paper, if necessary. Net proceeds of the issuances of Commercial Paper are expected to be used for general corporate purposes. Any outstanding Commercial Paper is classified as long-term debt in the accompanying Consolidated Balance Sheets since the Company has the intent and ability to refinance the Commercial Paper on a long-term basis using the Company's Revolving Credit Facility. The carrying value of Commercial Paper approximates its fair value, primarily due to its market interest rates, and is classified as Level 2 in the fair value hierarchy (Note 5).

***U.S. Senior Notes***

On March 3, 2025, the Company used a combination of cash on hand and borrowings under the U.S. Commercial Paper Program to repay the $400.0 aggregate principal amount of unsecured 2.050% Senior Notes due March 1, 2025 upon maturity.

On June 12, 2025, the Company issued $750.0 aggregate principal amount of unsecured 4.375% Senior Notes due June 12, 2028 (the "2028 Senior Notes"). Interest on the 2028 Senior Notes is payable semiannually on June 12 and December 12 of each year, which commenced on December 12, 2025. The Company used net proceeds from the 2028 Senior Notes to repay borrowings under the U.S. Commercial Paper Program and for general corporate purposes. During the year ended December 31, 2025, the Company incurred $4.6 of debt financing costs associated with the issuance of the 2028 Senior Notes.

[**Table of Contents**](#Toc_fix)

On November 10, 2025, the Company issued (i) $500.0 aggregate principal amount of unsecured Floating Rate Senior Notes due November 15, 2027 (the "Floating Rate Senior Notes"), (ii) $750.0 aggregate principal amount of unsecured 3.800% Senior Notes due November 15, 2027 (the "3.800% Senior Notes"), (iii) $750.0 aggregate principal amount of unsecured 3.900% Senior Notes due November 15, 2028 (the "3.900% Senior Notes"), (iv) $1,000.0 aggregate principal amount of unsecured 4.125% Senior Notes due November 15, 2030 (the "4.125% Senior Notes"), (v) $1,250.0 aggregate principal amount of unsecured 4.400% Senior Notes due February 15, 2033 (the "4.400% Senior Notes"), (vi) $1,600.0 aggregate principal amount of unsecured 4.625% Senior Notes due February 15, 2036 (the "4.625% Senior Notes") and (vii) $1,650.0 aggregate principal amount of unsecured 5.300% Senior Notes due November 15, 2055 (the "5.300% Senior Notes" and, together with the Floating Rate Senior Notes, the 3.800% Senior Notes, the 3.900% Senior Notes, the 4.125% Senior Notes, the 4.400% Senior Notes, the 4.625% Senior Notes and the 5.300% Senior Notes, the "November Senior Notes"). During the year ended December 31, 2025, the Company incurred $59.9 of debt financing costs associated with the issuance of the November Senior Notes.

The Floating Rate Senior Notes will bear interest at a floating rate per annum, reset quarterly, equal to Compounded SOFR, plus 0.53%. Interest on the Floating Rate Senior Notes is payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing on February 15, 2026. Interest on the 3.800% Senior Notes, 3.900% Senior Notes, 4.125% Senior Notes and 5.300% Senior Notes is payable semiannually on May 15 and November 15 of each year, commencing on May 15, 2026.

Interest on the April Senior Notes is payable semiannually on April 5 and October 5 of each year, which commenced on October 5, 2024. The Company used net proceeds from the April Senior Notes, together with a combination of cash on hand and borrowings under the U.S. Commercial Paper Program, to fund the cash consideration for the CIT acquisition in May 2024, along with the fees and expenses related thereto.

On October 31, 2024, the Company issued three series of unsecured senior notes (collectively, the "October Senior Notes"): (i) $250.0 aggregate principal amount of unsecured 5.050% Senior Notes due April 5, 2027 (the "Additional 2027 Senior Notes"), which constituted a further issuance of the Company's Original 2027 Senior Notes issued in April 2024, thus forming a single series with, and having the same terms (other than the issue date, issue price and the first interest payment date) as, the Original 2027 Senior Notes, and thus having a total aggregate principal amount of $700.0 of unsecured 5.050% Senior Notes due April 5, 2027 outstanding (the Original 2027 Senior Notes, together with the Additional 2027 Senior Notes collectively referred to as the "2027 Senior Notes"), (ii) $750.0 aggregate principal amount of unsecured 5.000% Senior Notes due January 15, 2035 (the "2035 Senior Notes") and (iii) $500.0 aggregate principal amount of unsecured 5.375% Senior Notes due November 15, 2054 (the "2054 Senior Notes"). Consistent with the Original 2027 Senior Notes, interest on the Additional 2027 Senior Notes is payable semiannually on April 5 and October 5 of each year, which commenced on April 5, 2025, commensurate with the timing of the remaining interest payments of the Original 2027 Senior Notes. Interest on the 2035 Senior Notes is payable semiannually on January 15 and July 15 of each year, which commenced on January 15, 2025. Interest on the 2054 Senior Notes is payable semiannually on May 15 and November 15 of each year, which commenced on May 15, 2025. On January 31, 2025, the Company used the net proceeds from the October Senior Notes, together with borrowings under the U.S. Commercial Paper Program and cash on hand, to fund the cash consideration for the Andrew acquisition, as discussed in further detail in Note 11 herein, along with the fees and expenses related thereto.

[**Table of Contents**](#Toc_fix)

All of the Company's outstanding senior notes in the United States (the "U.S. Senior Notes") are unsecured and rank equally in right of payment with all of the Company's other senior unsecured and unsubordinated indebtedness, including the Company's guarantee of the Euro Issuer's obligations under the Existing Euro Notes. Interest on each series of U.S. Senior Notes is payable semiannually, except for the Floating Rate Senior Notes for which interest is payable quarterly. The Company may, at its option, redeem some or all of any series of U.S. Senior Notes at any time, subject to certain terms and conditions, which include paying 100% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, and, with certain exceptions, a make-whole premium, except that the Company may not redeem the Floating Rate Senior Notes at its option prior to their maturity.

***Euro Senior Notes***

On June 16, 2025, the Company issued €600.0 (approximately $685.9 at date of issuance) aggregate principal amount of unsecured 3.125% Senior Notes due June 16, 2032 (the "2032 Euro Notes"). The 2032 Euro Notes are unsecured and rank equally in right of payment with all of the Company's other senior unsecured and unsubordinated indebtedness, including the Company's guarantee of the Euro Issuer's obligations under the Existing Euro Notes. Interest on the 2032 Euro Notes is payable annually on June 16 of each year, commencing on June 16, 2026. The Company used net proceeds from the 2032 Euro Notes to repay borrowings under the U.S. Commercial Paper Program and for general corporate purposes. During the year ended December 31, 2025, the Company incurred $4.5 of debt financing costs associated with the issuance of the 2032 Euro Notes.

The Euro Issuer has two outstanding unsecured senior notes issued in Europe. The Euro Issuer has €500.0 (approximately $545.4 at date of issuance) aggregate principal amount of unsecured 0.750% Senior Notes due May 4, 2026, which were issued in May 2020 (the "2026 Euro Notes" or the "0.750% Euro Senior Notes"). The net proceeds of the 2026 Euro Notes were used to repay amounts outstanding under the then existing revolving credit facility. The Euro Issuer also has €500.0 (approximately $574.6 at date of issuance) aggregate principal amount of unsecured 2.000% Senior Notes due October 8, 2028, which were issued in October 2018 (the "2028 Euro Notes" or the "2.000% Euro Senior Notes", together with the 2026 Euro Notes, the "Existing Euro Notes," and the Existing Euro Notes, together with the 2032 Euro Notes, the "Euro Notes", and together with the U.S. Senior Notes, the "Senior Notes"). The net proceeds of the 2028 Euro Notes were used to repay a portion of the outstanding amounts under our Commercial Paper Programs, with the remainder of the net proceeds being used for general corporate purposes. The Existing Euro Notes are unsecured and rank equally in right of payment with all of the Euro Issuer's senior unsecured and unsubordinated indebtedness and are fully and unconditionally guaranteed on a senior unsecured basis by the Company. Interest on each series of Euro Notes is payable annually on May 4 and October 8 of each year, respectively. The Company may, at its option, redeem some or all of either series of Existing Euro Notes at any time, subject to certain terms and conditions, which include paying 100% of the principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of redemption, and, with certain exceptions, a make-whole premium.

The fair value of each series of Senior Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 5). The Senior Notes impose certain obligations on the Company and prohibit various actions by the Company unless it satisfies certain financial requirements.

The maturity of the Company's debt (exclusive of unamortized deferred debt issuance costs as of December 31, 2025) over each of the next five years ending December 31 and thereafter, is as follows:

---

| | |
|:---|:---|
| 2026 | $937.2 |
| 2027 | 1950.9 |
| 2028 | 2084.6 |
| 2029 | 949.6 |
| 2030 | 1898.7 |
| Thereafter  | 7780.9 |
|  | $15601.9 |

As of December 31, 2025, the Company had approximately $144.7 of uncommitted standby letter of credit facilities, of which $61.3 were issued.

***Note 5—Fair Value Measurements***

Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. These requirements establish market or observable inputs as the preferred source of values. Assumptions based on hypothetical transactions are used in the absence of market inputs. The Company does not have any non-financial instruments accounted for at fair value on a recurring basis.

The valuation techniques required are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Quoted prices for identical instruments in active markets.

Level 2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Significant inputs to the valuation model are unobservable.

The Company believes that the assets and liabilities currently subject to such standards with fair value disclosure requirements are primarily (i) debt instruments, (ii) pension plan assets, and (iii) assets acquired and liabilities and noncontrolling interests assumed as part of acquisition accounting, which are discussed in Note 4, Note 9 and Note 11, respectively, herein, along with short- and long-term investments and derivative instruments, discussed below. Substantially all of the Company's short- and long-term investments consist of certificates of deposit, which are considered as Level 2 in the fair value hierarchy. Long-term investments are recorded in Other long-term assets in the accompanying Consolidated Balance Sheets. The carrying amounts of these short- and long-term instruments, the vast majority of which are in non-U.S. bank accounts, approximate their respective fair values. The Company's derivative instruments primarily consist of foreign exchange forward contracts, which are valued using bank quotations based on market observable inputs, such as forward and spot rates, and are therefore classified as Level 2 in the fair value hierarchy. The impact of the credit risk related to these derivative financial assets is immaterial.

The Company reviews the fair value hierarchy classifications on a quarterly basis and determines the appropriate classification of such assets and liabilities subject to the fair value hierarchy standards based on, among other things, the ability to observe valuation inputs. The fair values of the Company's financial and non-financial assets and liabilities subject to such standards at December 31, 2025 and December 31, 2024 are as follows:

The Company utilizes foreign exchange forward contracts, hedging instruments accounted for as cash flow hedges, in the management of foreign currency exposures. In addition, the Company also enters into foreign exchange forward contracts, accounted for as net investment hedges, to hedge our exposure to variability in the U.S. dollar equivalent of the net investments in certain foreign subsidiaries. As of December 31, 2025 and 2024, the Company had no outstanding foreign exchange forward contracts accounted for as either net investment hedges or cash flow hedges.

[**Table of Contents**](#Toc_fix)

However, in June 2025, the Company issued the 2032 Euro Notes as discussed in Note 4, which have been designated as a hedge of the Company's net investment in certain foreign subsidiaries. The effect of translating the 2032 Euro Notes into U.S. Dollars is recorded in Accumulated other comprehensive income (loss) and remains there until the underlying net investment is sold or substantially liquidated. We assessed the effectiveness of the net investment hedge at the inception of the hedging relationship and will assess quarterly thereafter. As of December 31, 2025, the net investment hedge was assessed and deemed to be effective.

As of December 31, 2025 and 2024, the fair value of such foreign exchange forward contracts in the table above consisted of various outstanding foreign exchange forward contracts that are not designated as hedging instruments. The fair value of the Company's forward contracts are recorded within Prepaid expenses and other current assets, Other long-term assets, Other accrued expenses and Other long-term liabilities in the accompanying Consolidated Balance Sheets, depending on their value and remaining contractual period.

In August 2025, the Company entered into $1,500.0 10-year and $1,000.0 30-year notional treasury lock derivative instruments to hedge interest rate risk prior to the issuance of the November Senior Notes, as discussed in Note 4 herein. Both treasury locks were designated as cash flow hedges. The treasury locks were settled in the fourth quarter of 2025 upon the issuance of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively, for a cumulative loss of $88.0 ($67.4 after-tax). The cumulative after-tax loss was recorded in Accumulated other comprehensive income (loss) and is being amortized to Interest expense over the terms of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively.

Certain acquisitions may result in noncontrolling interest holders who, in certain cases, are entitled to a put option, giving them the ability to put some or all of their redeemable interest in the shares of the acquiree to the Company. Specifically, if exercised by the noncontrolling interest holder, Amphenol would be required to purchase some or all of the option holder's redeemable interest, at a redemption price during specified time period(s) stipulated in the respective acquisition agreement. The redeemable noncontrolling interests recorded on the accompanying Consolidated Balance Sheets relate to recent acquisitions, which, based on the terms of the respective acquisition agreements, will remain in temporary equity until the applicable put option is either exercised or expires. When noncontrolling option holders exercise their put options, the Company is required to acquire its entire redeemable noncontrolling interests, or portions thereof, then outstanding. The redemption value of the redeemable noncontrolling interests is generally calculated using Level 3 unobservable inputs based on a multiple of earnings, which, for the redeemable noncontrolling interests currently outstanding, approximate fair value. As such, the redemption value is classified as Level 3 in the fair value hierarchy and is recorded as Redeemable noncontrolling interests on the Consolidated Balance Sheets as of December 31, 2025 and 2024. A rollforward of the Redeemable noncontrolling interests for the years ended December 31, 2025, 2024 and 2023 is included in the accompanying Consolidated Statements of Changes in Equity.

With the exception of the fair value of the assets acquired and liabilities assumed in connection with acquisition accounting, the Company does not have any other significant financial or non-financial assets and liabilities that are measured at fair value on a non-recurring basis. For further discussion and related policies regarding the Company's short- and long-term investments, derivative financial instruments, and redeemable noncontrolling interests, refer to Note 1 herein.

For the years ended December 31, 2025, 2024 and 2023, stock option exercise activity had the impact of decreasing our Provision for income taxes by $246.6, $142.6 and $82.4, respectively, and decreasing our effective tax rate by the basis points in the table above. Total acquisition-related expenses, as discussed in further detail in Note 11 herein, had the aggregate impact of increasing our effective tax rate by approximately 20 basis points, 30 basis points and 20 basis points for the years ended December 31, 2025, 2024 and 2023, respectively. For the year ended December 31, 2025, a discrete tax item of $100.0 related to a charge recorded for notices received by certain subsidiaries in China from relevant tax authorities challenging certain of the Company's tax positions taken over up to an eight-year period had the effect of increasing our effective tax rate by approximately 180 basis points. For the year ended December 31, 2024, a

The Company includes estimated interest and penalties related to unrecognized tax benefits in the provision for income taxes. During the years ended December 31, 2025, 2024 and 2023, the provision for income taxes included a net (benefit) expense of $(3.8), ($4.2) and $5.8, respectively, in estimated interest and penalties. As of December 31, 2025, 2024 and 2023, the liability for unrecognized tax benefits included $36.9, $37.7 and $41.8, respectively, for tax-related interest and penalties.

The Company operates in the U.S. and numerous foreign taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. With few exceptions, the Company is subject to income tax examinations by tax authorities for the years 2017 and after. The Company is generally not able to precisely estimate the ultimate settlement amounts or timing until the close of an audit. The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by tax authorities and may not be fully sustained, despite the Company's belief that the underlying tax positions are fully supportable. As of December 31, 2025 and

[**Table of Contents**](#Toc_fix)

2024, the amount of unrecognized tax benefits, including penalties and interest, which if recognized would impact the effective tax rate, was approximately $311.7 and $209.7, respectively. Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including the progress of tax audits and the closing of statutes of limitations. Based on information currently available, management anticipates that over the next 12-month period, audit activity could be completed and statutes of limitations may close relating to existing unrecognized tax benefits of approximately $108.9.

In addition, in 2025, certain of the Company's subsidiaries based in China received notices from relevant tax authorities challenging certain of the Company's tax positions taken over up to an eight-year period. Although the Company believes its tax positions are appropriate and is currently discussing the matter with the relevant tax authorities, the Company has recorded a charge of $100.0 in the fourth quarter of 2025. The $100.0 charge represents the Company's current best estimate of the costs that may be incurred to resolve this matter; however, the range of potential costs is estimated to be $100.0 to approximately $300.0. The Company is unable to estimate the timing for resolution of this matter.

*Inflation Reduction Act of 2022*

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IRA"), a tax and spending package that introduced 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, was enacted into law. Companies were required to reassess their valuation allowances for certain affected deferred tax assets in the period of enactment but did 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 years ended December 31, 2025 and 2024. 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.

*H.R. 1*

On July 4, 2025, the United States federal government enacted the tax and spending bill H.R. 1. This legislation contains changes to previously enacted provisions of the Internal Revenue Code and provides for extensions of certain expiring tax provisions included in the Tax Act. Certain corporate tax provisions in H.R. 1 were enacted with retroactive effect to January 1, 2025. H.R. 1 did not have a material impact on our effective tax rate for the year ended December 31, 2025. The Company continues to evaluate the corporate tax provisions contained within H.R. 1, and the future impact of H.R. 1 depends on several factors, including interpretive regulatory guidance, which has not yet been released.

***Note 7—Equity***

*Stock-Based Compensation:*

For the years ended December 31, 2025, 2024 and 2023, the Company's Income before income taxes was reduced by stock-based compensation expense of $135.4, $109.5, and $99.0, respectively, the expense of which is included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Income. In addition, for the years ended December 31, 2025, 2024 and 2023, the Company recognized aggregate income tax benefits (associated with stock-based compensation) of $261.3, $154.1, and $92.4, respectively, in Provision for income taxes in the accompanying Consolidated Statements of Income. These aggregate income tax benefits during the years ended December 31, 2025, 2024 and 2023 include excess tax benefits of $246.6, $142.6, and $82.4, respectively, from option exercises. The impact associated with recognizing excess tax benefits from option exercises in the provision for income taxes on our consolidated financial statements could result in significant fluctuations in our effective tax rate in the future, since the provision for income taxes will be impacted by the timing and intrinsic value of future stock-based compensation award exercises.

***Stock Options***

In May 2017, the Company adopted the 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the "2017 Employee Option Plan"), which provided for the issuance of 120,000,000 shares.

The Amended 2017 Employee Option Plan was approved by the Company's stockholders and became effective on May 19, 2021. As of December 31, 2025, there were 47,388,446 shares of Common Stock available for the granting of additional stock options under the 2017 Option Plan. Prior to the approval of the 2017 Employee Option Plan, the Company issued stock options under the 2009 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries, and its amendment (the "2009 Employee Option Plan"). No additional stock options will be granted under the 2009 Employee Option Plan.

During the years ended December 31, 2025, 2024 and 2023, the following activity occurred under the Company's option plans:

---

| | | | |
|:---|:---|:---|:---|
|  | **2025** | **2024** | **2023** |
| Total intrinsic value of stock options exercised | $1813.5 | $980.3 | $559.6 |
| Total fair value of stock options vested | 116.1 | 99.7 | 90.0 |

---

As of December 31, 2025, the total compensation cost related to non-vested options not yet recognized was approximately $355.6 with a weighted average expected amortization period of 3.45 years.

The grant-date fair value of each option grant under the 2009 Employee Option Plan and the 2017 Option Plan is estimated using the Black-Scholes option pricing model. The grant-date fair value of each share grant is determined based on the closing share price of the Company's Common Stock on the date of the grant. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model for option grants requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility is calculated based on the historical volatility of the Common Stock and implied volatility derived from related exchange traded options. The average expected life is based on the contractual term of the option and expected exercise and historical experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issuances with a remaining term equal to the expected life assumed at the date of grant. The expected annual dividend per share is based on the Company's dividend rate.

The fair value of stock options has been estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

---

| | | | |
|:---|:---|:---|:---|
|  | **2025** | **2024** | **2023** |
| Risk free interest rate  | 4.1% | 4.4% | 3.8% |
| Expected life  | 4.9<br> years | 4.9<br> years | 4.9<br> years |
| Expected volatility  | 27.1% | 28.0% | 28.0% |
| Expected dividend yield  | 1.0% | 1.0% | 1.0% |

From January 1, 2026 to January 31, 2026, the Company repurchased 0.3 million additional shares of its Common Stock for $44.2, and, as of February 1, 2025, the Company has remaining authorization to purchase up to $826.9 of its Common Stock under the 2024 Stock Repurchase Program. The timing and amount of any future repurchases 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.

On April 27, 2021, the Board authorized a stock repurchase program under which the Company could purchase up to $2,000.0 of its Common Stock during the three-year period ending April 27, 2024 (the "2021 Stock Repurchase Program"). During the year ended December 31, 2024, the Company repurchased 4.1 million shares of its Common Stock for $225.6 under the 2021 Stock Repurchase Program. All of the repurchased shares under the 2021 Stock Repurchase Program during 2024 have been retired by the Company. As a result of these repurchases, the Company completed all repurchases authorized under the 2021 Stock Repurchase Program, and, therefore, the 2021 Stock Repurchase Program has terminated.

*Dividends:*

Contingent upon declaration by the Board, the Company pays a quarterly dividend on shares of its Common Stock.

For the years ended December 31, 2025, 2024 and 2023, as it relates to the Company's cash flow hedges, which is comprised of foreign exchange forward contracts, the amounts recognized in Accumulated other comprehensive income (loss) associated with foreign exchange forward contracts, as well as the amounts reclassified from Accumulated other comprehensive income (loss) to foreign exchange gain (loss), included in Cost of sales in the accompanying Consolidated Statements of Income, were not material. There were no reclassifications associated with net investment hedges from Accumulated other comprehensive income (loss) to earnings during the years presented in the table above. While there were no outstanding cash flow hedges as of December 31, 2025 and 2024, any amounts included in Accumulated other comprehensive income (loss) associated with cash flow hedges are generally expected to be reclassified into earnings within the following 12 months. In August 2025, the Company entered into $1,500.0 10-year and $1,000.0 30-year notional treasury lock derivative instruments to hedge interest rate risk prior to the issuance of the November Senior Notes, as discussed in Notes 4 and 5 herein. The treasury locks were settled in the fourth quarter of 2025 upon the issuance of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively, for a cumulative after-tax loss of $67.4, which was recorded in Accumulated other comprehensive income (loss) and is being amortized to Interest expense over the terms of the 4.625% Senior Notes and the 5.300% Senior Notes, respectively. The amounts reclassified from Accumulated other comprehensive income (loss) to earnings, related to pension and other postretirement benefit plans in the table above, are reported within Other income (expense), net in the Consolidated Statements of Income, the vast majority of which is related to the amortization of actuarial losses associated with our defined benefit plans. The amortization of actuarial losses is included in the computation of net pension expense discussed in more detail within Note 9 herein.

***Note 8—Earnings Per Share***

The following is a reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding, which were used to calculate the earnings per share (basic and diluted) for the years ended December 31, 2025, 2024 and 2023:

Excluded from the computations above were anti-dilutive common shares (primarily related to outstanding stock options) of 5.6 million, 4.8 million, and 14.4 million for the years ended December 31, 2025, 2024 and 2023, respectively.

***Note 9—Benefit Plans and Other Postretirement Benefits***

*Defined Benefit Plans*

The Company and certain of its domestic subsidiaries have defined benefit pension plans (the "U.S. Pension Plans"), which cover certain U.S. employees and which represent the majority of the plan assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Pension Plans' benefits are generally based on years of service and compensation and are generally noncontributory. The majority of U.S. employees are not covered by the U.S. Pension Plans and are instead covered by various defined contribution plans. The Company also has an unfunded Supplemental Employee Retirement Plan ("SERP" and, together with the U.S. Pension Plans, "U.S. Plans"), which provides for the payment of the portion of annual pension that cannot be paid from the retirement plan as a result of regulatory limitations on average compensation for purposes of the benefit computation. Certain foreign subsidiaries have defined benefit plans covering their employees (the "Foreign Plans" and, together with the U.S. Plans, the "Plans"). The largest foreign pension plan, in accordance with local regulations, is unfunded and had a projected benefit obligation

[**Table of Contents**](#Toc_fix)

of approximately $70.9 and $72.2 at December 31, 2025 and 2024, respectively. Total required contributions to be made during 2026 for the unfunded Foreign Plans are included in Other accrued expenses in the accompanying Consolidated Balance Sheets and in the tables below.

The following is a summary of the Company's defined benefit plans' funded status as of the most recent actuarial valuations as of December 31 of each year.

---

The projected benefit obligation decreased slightly in 2025, primarily due to benefits paid during the year, which were largely offset by interest cost and the impact of foreign exchange. The projected benefit obligation decreased in 2024, primarily due to benefits paid and actuarial gains resulting from the impact of higher discount rates on our projected benefit obligation, partially offset by interest cost. The accumulated benefit obligation for the Company's defined benefit pension plans was $491.4 and $492.5 at December 31, 2025 and 2024, respectively. As of December 31, 2025 and 2024, the accumulated benefit obligation for the U.S. Plans was $337.4 and $341.3, respectively, and for the Foreign Plans was $154.0 and $151.2, respectively.

The pension expense for the Plans is calculated based upon a number of actuarial assumptions established on January 1 of the applicable year, including mortality projections as well as a weighted average discount rate, rate of increase in future compensation levels and an expected long-term rate of return on the respective Plans' assets which are detailed in the table above. The Company records service costs in the same line item as the respective employee compensation costs and within operating income, while all non-service costs are reported separately within Other income (expense), net in the Consolidated Statements of Income.

[**Table of Contents**](#Toc_fix)

The discount rate used by the Company for valuing pension liabilities is based on a review of high quality corporate bond yields with maturities approximating the remaining life of the projected benefit obligations. The weighted average discount rate for the U.S. Plans on this basis was 5.28% and 5.53% at December 31, 2025 and 2024, respectively. The decrease in the discount rate for the U.S. Plans resulted in an increase in the benefit obligation of approximately $7.0 at December 31, 2025. The weighted average discount rate for the Foreign Plans was 4.60% and 4.13% at December 31, 2025 and 2024, respectively. The increase in the discount rate for the Foreign Plans did not have a material effect on the benefit obligation at December 31, 2025. The Company calculates its service and interest costs by applying a split discount rate approach under which specific spot rates along the selected yield curve are applied to the relevant projected cash flows as the Company believes this method more precisely measures its obligations. The mortality assumptions used by the Company reflect commonly used mortality tables and improvement scales for each plan and increased life expectancies for plan participants.

The primary investment objective of the Plans is to ensure an adequate pool of assets to support the benefit obligations to participants, retirees and beneficiaries. Over time, the Plans have aimed to earn a rate of return on assets greater than the liability discount rate, with a prudent level of risk and diversification. For the U.S. Plans, this has resulted in assets exceeding benefit obligations. The target asset allocations for the U.S. Plans were 15% equities and 85% fixed income as of December 31, 2025 and 2024, and the Company expects to maintain these target asset allocations for the U.S. Plans for 2026. Short-term strategic ranges for investments will continue to be established within these new long-term target percentages. The Company regularly reviews the actual asset allocation and periodically rebalances investments to its targeted allocation when considered appropriate.

The Company invests in a diversified investment portfolio through various investment managers and evaluates its plan assets for the existence of concentration risks. As of December 31, 2025, there were no significant concentrations of risks in the Company's defined benefit plan assets. The Company does not invest nor instruct investment managers to invest pension assets in Amphenol securities. The Plans may indirectly hold the Company's securities as a result of external investment management in certain commingled funds. Such holdings would not be material relative to the Plans' total assets. The Company's Foreign Plans primarily invest in equity and debt securities and insurance contracts, as determined by each Plans' Trustees or investment managers.

In developing the expected long-term rate of return assumption for the U.S. Plans, the Company relies primarily on projected long-term asset returns by asset class prepared annually by our investment consultants. For 2025, the expected long-term rate of return on the U.S. Plans' assets was based on an asset allocation assumption of approximately 15% with equity managers (with an expected long-term rate of return of approximately 5.9%) and 85% with fixed income managers (with an expected long-term rate of return of approximately 5.4%).

The Company's Plan assets, the vast majority of which relate to the U.S. Plans, are reported at fair value and classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The process requires judgment and may have an effect on the placement of the Plan assets within the fair value measurement hierarchy. The fair values of the Company's pension Plans' assets at December 31, 2025 and 2024 by asset category are as follows (refer to Note 5 for definitions of Level 1, 2 and 3 inputs):

Equity securities primarily consist of publicly traded U.S. and non-U.S. equities. Publicly traded securities are valued at the last trade or closing price reported in the active market in which the individual securities are traded. Certain equity securities held in commingled funds are valued at unitized net asset value ("NAV") based on the fair value of the underlying net assets owned by the funds. Alternative investment funds include investments in hedge funds including fund of fund products.

Fixed income securities primarily consist of government securities and corporate bonds. They are valued at the closing price in the active market or at quotes obtained from brokers/dealers or pricing services. Certain fixed income securities held within commingled funds are valued based on the fair value of the underlying net assets of the funds, as determined by the custodian of the funds.

The Level 2 pension plan assets are comprised primarily of pooled funds valued using published prices based off of observable market data.

[**Table of Contents**](#Toc_fix)

The Level 3 pension plan assets as of December 31, 2025 and 2024 included in the table above primarily consist of contracts with insurance companies related to certain foreign plans. The insurance contracts generally include guarantees in accordance with the policy purchased. Our valuation of Level 3 assets is based on insurance company or third-party actuarial valuations, representing an estimation of the surrender or market values of the insurance contract between the Company and the insurance companies. The following table sets forth a summary of changes of the fair value of the Level 3 pension plan assets for the years ended December 31, 2025 and 2024:

---

| | | |
|:---|:---|:---|
|  | **2025** | **2024** |
| Balance on January 1 | $17.8 | $19.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unrealized (losses) gains, net | (0.5) | 0.6 |

The Company made cash contributions to the Plans of $4.8, $4.9, and $5.4 in 2025, 2024, and 2023, respectively. There is no current requirement for cash contributions to any of the U.S. Plans, and the Company plans to evaluate annually, based on actuarial calculations and the investment performance of the Plans' assets, the timing and amount of cash contributions in the future, if any.

Benefit payments related to the Plans above, including those amounts to be paid out of Company assets and reflecting future expected service as appropriate, are expected to be as follows:

---

| | | | |
|:---|:---|:---|:---|
| <br>**Year** | **U.S.**<br>**Plans** | **Foreign**<br>**Plans** | <br>**Total** |
| 2026 | $33.2 | $8.2 | $41.4 |
| 2027 | 28.0 | 8.6 | 36.6 |

Certain foreign subsidiaries of the Company offer certain benefits under local statutory plans which are excluded from the tables above. The net liability for such plans was $37.8 and $30.0 as of December 31, 2025 and 2024, respectively, the majority of which is included within Accrued pension and postretirement benefit obligations in the accompanying Consolidated Balance Sheets.

*Other Postretirement Benefit Plans*

The Company maintains self-insurance programs for that portion of its health care and workers compensation costs not covered by insurance. The Company also provides certain health care and life insurance benefits to certain eligible retirees in the U.S. through postretirement benefit ("OPEB") programs. The Company's share of the cost of such plans for most participants is fixed, and any increase in the cost of such plans will be the responsibility of the retirees. The Company funds the benefit costs for such plans on a pay-as-you-go basis. As of December 31, 2025 and 2024, the total liability associated with postretirement benefit obligations was approximately $3.2 and $3.5, respectively, the majority of which is included in Accrued pension and postretirement benefit obligations on the accompanying Consolidated Balance Sheets. The weighted average discount rate used to determine the projected benefit obligation as of December 31, 2025 and 2024 was 5.42% and 5.58%, respectively. Net postretirement benefit expense on the accompanying Consolidated Statements of Income was not material for each of the years ended December 31, 2025, 2024 and 2023. Since the Company's obligation for postretirement medical plans is fixed and since the benefit obligation and the net postretirement benefit expense are not material in relation to the Company's financial condition or results of operations, the Company believes any change in medical costs from that estimated will not have a significant impact on the Company.

*Defined Contribution Plans*

The Company offers various defined contribution plans for certain U.S. and foreign employees. Participation in these plans is based on certain eligibility requirements. The Company matches employee contributions to the U.S. defined contribution plans up to a maximum of 7% of eligible compensation. The Company provided matching contributions to the U.S. defined contribution plans of approximately $35.9, $24.7 and $24.0 in 2025, 2024 and 2023, respectively.

***Note 10—Leases***

*Operating Leases*

For the years ended December 31, 2025, 2024 and 2023, total operating lease cost was $201.5, $156.2 and $127.1, respectively, which include an immaterial amount of variable lease cost, and is recorded in Cost of sales and Selling, general and administrative expenses, dependent on the nature of the leased asset. Other than variable lease cost, operating lease cost is recognized on a straight-line basis over the lease term. The following summarizes (i) the future minimum undiscounted lease payments under non-cancelable operating leases for each of the next five years and thereafter, incorporating the practical expedient to account for lease and non-lease components as a single lease component for our existing real estate leases and (ii) a reconciliation of the undiscounted lease payments to the present value of the lease liabilities recognized, all as of December 31, 2025:

Lease contracts that we have executed but which have not yet commenced as of December 31, 2025 were not material, and are excluded from the tables above. The Company does not generally enter into leases involving the construction or design of the underlying asset, and nearly all of the assets we lease are not specialized in nature. Our lease agreements generally do not include residual value guarantees nor do we enter into sublease arrangements with external parties.

*Finance Leases*

In rare circumstances, the Company may enter into finance leases for specific equipment used in manufacturing, in which the Company takes ownership of the asset upon the end of the lease. The Company records its finance leases within Property, plant and equipment, net, Current portion of long-term debt and Long-term debt on the accompanying Consolidated Balance Sheets. The Company's finance leases and related depreciation and interest expense, cash flows and impact on the Company's consolidated financial statements were not material individually or in the aggregate as of and for the years ended December 31, 2025, 2024 and 2023.

***Note 11—Acquisitions***

*2025 Acquisitions*

During the year ended December 31, 2025, the Company completed five acquisitions (the "2025 Acquisitions"), including the acquisitions of Andrew and Trexon, for approximately $3,818.6, net of cash acquired. The Andrew acquisition has been included in the Communications Solutions segment, three acquisitions including Trexon have been included in the Harsh Environment Solutions segment, and one acquisition has been included in the Interconnect and Sensor Systems segment. The 2025 Acquisitions were each funded using cash on hand, proceeds from the October Senior Notes, borrowings under the U.S. Commercial Paper Program, or a combination thereof. The Company is in the process of analyzing and completing the allocation of the fair value of the assets acquired and liabilities assumed for each of the 2025 Acquisitions. Since the current purchase price allocations for such acquisitions are based on preliminary assessments made by management as of December 31, 2025, the acquisition accounting is subject to final adjustments, and it is possible that the final assessments of values may differ from the Company's preliminary assessments. The operating results of the 2025 Acquisitions were included in the Consolidated Statements of Income since their respective dates of acquisition. Pro forma financial information, as well as further details regarding the purchase price allocations related to these acquisitions, have not been presented, since the 2025 Acquisitions were not material, either individually or in the aggregate, to the Company's financial results.

*Acquisition of Andrew*

On January 31, 2025, pursuant to a purchase agreement dated July 18, 2024, the Company completed the acquisition of Andrew for an aggregate purchase price of $2,022.7, net of cash acquired and subject to customary post-closing adjustments. The Andrew business provides communications network solutions, including distributed antenna systems. Andrew's wide range of products add advanced antenna and associated interconnect products, technologies and capabilities, which management believes are highly complementary to Amphenol's existing product portfolio for next-generation wireless networks. Andrew has been included in the Communications Solutions segment.

As of December 31, 2025, the Andrew acquisition resulted in the recognition of $874.0 of goodwill and $800.0 of definite-lived intangible assets, comprised of customer relationships, proprietary technology and acquired backlog, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities assumed. These definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit as reflected by the future net cash inflows, with the acquired customer relationships and proprietary technology having useful lives ranging from 12 to 15 years and the acquired backlog having a useful life of approximately 0.25 years. The excess purchase price over the fair value of the underlying net assets acquired (net of liabilities assumed) was allocated to goodwill, which primarily represents the value of the assembled workforce along with other intangible assets that do not qualify for separate recognition. The Company expects that $672.8 of the goodwill recognized from the Andrew acquisition will be deductible for tax purposes.

[**Table of Contents**](#Toc_fix)

*Acquisition of Trexon*

On November 6, 2025, pursuant to a definitive agreement, dated August 18, 2025, the Company completed the acquisition of Trexon, for an aggregate purchase price of $1,050.3, net of cash acquired and subject to customary post-closing adjustments. Trexon expands the Company's high-reliability interconnect and cable assembly capabilities, primarily for the defense market. Trexon has been included in the Harsh Environment Solutions segment.

As of December 31, 2025, the Trexon acquisition resulted in the recognition of $708.2 of goodwill and $318.0 of definite-lived intangible assets, comprised of customer relationships and acquired backlog, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities assumed. These definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit as reflected by the future net cash inflows, with the acquired customer relationships having useful lives of 18 years and the acquired backlog having a useful life of approximately 0.5 years. The excess purchase price over the fair value of the underlying net assets acquired (net of liabilities assumed) was allocated to goodwill, which primarily represents the value of the assembled workforce along with other intangible assets that do not qualify for separate recognition. The Company expects that none of the goodwill recognized from the Trexon acquisition will be deductible for tax purposes.

*2024 Acquisitions*

During the year ended December 31, 2024, the Company completed two acquisitions (the "2024 Acquisitions"), including the acquisition of Carlisle Interconnect Technologies ("CIT") for $2,156.4, net of cash acquired. Both acquisitions have been included in the Harsh Environment Solutions segment. The 2024 Acquisitions were each funded using cash on hand, proceeds from the April Senior Notes or borrowings under the U.S. Commercial Paper Program, or a combination thereof.

As of December 31, 2025, the 2024 Acquisitions resulted in the recognition of $1,195.1 of goodwill and $576.0 of definite-lived intangible assets, comprised of customer relationships and acquired backlog, with the remainder of the purchase price being allocated to the other identifiable assets acquired and liabilities assumed. These definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit as reflected by the future net cash inflows, with the acquired customer relationships having useful lives ranging from 8 to 15 years and the acquired backlog having a useful life of approximately 0.4 years. The excess purchase price over the fair value of the underlying assets acquired (net of liabilities assumed) was allocated to goodwill, which primarily represents the value of the assembled workforce along with other intangible assets acquired that do not qualify for separate recognition. The Company expects that $61.2 of the goodwill recognized from the 2024 Acquisitions will be deductible for tax purposes.

In 2025, the Company completed the acquisition accounting, including the analyses of fair value of assets acquired and liabilities assumed for both of the 2024 Acquisitions, and the final assessments of values did not differ materially from their previous preliminary assessments. The operating results of the 2024 Acquisitions were included in the Consolidated Statements of Income since their respective dates of acquisition. Pro forma financial information, as well as further details regarding the purchase price allocations related to these acquisitions, were not presented, since the 2024 Acquisitions were not material, either individually or in the aggregate, to the Company's financial results.

*Acquisition of CIT*

On May 21, 2024, the Company completed the acquisition of CIT for $1,995.3, net of cash acquired and subject to customary post-closing adjustments. The Company funded the CIT acquisition through a combination of net proceeds from the April Senior Notes, as discussed in Note 4 herein, together with borrowings under the U.S. Commercial Paper Program and cash on hand. CIT, headquartered in St. Augustine, FL, is a leading global supplier of harsh environment interconnect solutions, primarily to the commercial aerospace, defense and industrial end markets. CIT's wide range of products include wire and cable, cable assemblies, contacts, connectors and sensors, which management believes are highly complementary to Amphenol's existing interconnect and sensor solutions.

As of December 31, 2025, the CIT acquisition resulted in the recognition of $1,119.7 of goodwill and $543.0 of definite-lived intangible assets, with the remainder of the purchase price being allocated to other identifiable assets acquired and liabilities assumed. Of the acquired definite-lived intangible assets, approximately $488.0 and $55.0 were assigned to customer relationships and acquired backlog, respectively. The acquired customer relationships and acquired backlog have a weighted average useful life of approximately 15 years and 0.4 years, respectively. These

[**Table of Contents**](#Toc_fix)

definite-lived intangible assets are being amortized based upon the underlying pattern of economic benefit as reflected by the future net cash inflows. The excess purchase price over the fair value of the underlying assets acquired (net of liabilities assumed) was allocated to goodwill, which primarily represents the value of the assembled workforce along with other intangible assets acquired that do not qualify for separate recognition. The Company expects that none of the goodwill recognized from the CIT acquisition will be deductible for tax purposes.

*2023 Acquisitions*

During the year ended December 31, 2023, the Company completed 10 acquisitions (the "2023 Acquisitions") for approximately $970.4, net of cash acquired. Five of the acquisitions were included in the Harsh Environment Solutions segment, three acquisitions were included in the Interconnect and Sensor Systems segment, and two acquisitions were included in the Communications Solutions segment. The 2023 Acquisitions were each funded using cash on hand or borrowings under our Commercial Paper Programs, or a combination thereof. One of the 2023 Acquisitions, which closed in the second quarter of 2023, represented a bargain purchase, where the estimated fair value of assets acquired, net of liabilities assumed, exceeded the purchase price. The Company recognized a non-cash gain of $5.4 on the bargain purchase acquisition during the year ended December 31, 2023, which was recorded separately in the Company's Consolidated Statements of Income.

*Acquisition-related Expenses*

In 2025 the Company incurred $181.2 ($148.8 after-tax) of acquisition-related expenses, comprised primarily of (i) the non-cash amortization related to the value associated with acquired backlog resulting from the Andrew and Trexon acquisitions and external transaction costs related to acquisitions (such acquisition-related expenses aggregating $103.4 are presented separately in the Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $77.8 associated with the Andrew acquisition (such costs are recorded in Cost of Sales in the Consolidated Statements of Income). In 2024, the Company incurred $145.6 ($119.3 after-tax) of acquisition-related expenses, comprised primarily of (i) external transaction costs associated with acquisitions and the non-cash amortization of $55.0 related to the value associated with acquired backlog resulting from the CIT acquisition (such acquisition-related expenses aggregating $127.4 are presented separately in the accompanying Consolidated Statements of Income) and (ii) the non-cash amortization of acquisition-related inventory step-up costs of $18.2 associated with the CIT acquisition (such costs are recorded in Cost of sales in the accompanying Consolidated Statements of Income). In 2023, the Company incurred $34.6 ($30.2 after-tax) of acquisition-related expenses, comprised primarily of external transaction costs associated with the 2023 Acquisitions, as well as the non-cash amortization of $12.4 related to the value associated with acquired backlog resulting from three of the 2023 Acquisitions. Such acquisition-related expenses incurred in 2023 were presented separately in the accompanying Consolidated Statements of Income.

***Note 12—Goodwill and Other Intangible Assets***

The changes in the carrying amount of goodwill by segment were as follows:

---

|:---|:---|:---|:---|:---|
|  | <br>**Communications**<br>**Solutions** | **Harsh**<br>**Environment**<br>**Solutions** | **Interconnect**<br>**and Sensor**<br>**Systems** | <br>**Total** |
| **Goodwill at December 31, 2023** | $2977.5 | $2009.3 | $2105.6 | $7092.4 |
| Acquisition-related | (4.5) | 1192.3 | 58.9 | 1246.7 |
| Foreign currency translation | (21.5) | (21.6) | (59.8) | (102.9) |
| **Goodwill at December 31, 2024** | 2951.5 | $3180.0 | 2104.7 | 8236.2 |
| Acquisition-related | 872.4 | 1052.6 | 236.6 | 2161.6 |

| **Goodwill at December 31, 2025** | $3858.6 | $4270.2 | $2446.6 | $10575.4 |

---

The increase in goodwill during 2025 was primarily driven by goodwill recognized from the 2025 Acquisitions, in particular, the Andrew and Trexon acquisitions, and foreign currency translation. The increase in goodwill during 2024 was primarily driven by goodwill recognized from the 2024 Acquisitions, in particular, the CIT acquisition, partially offset by foreign currency translation.

[**Table of Contents**](#Toc_fix)

Other than goodwill noted above, the Company's intangible assets as of December 31, 2025 and 2024 were as follows:

---

| | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|
|  | **December 31, 2025** | **December 31, 2025** | **December 31, 2025** | **December 31, 2025** | **December 31, 2024** | **December 31, 2024** | **December 31, 2024** |

| Total |  | $3290.6 | $1049.2 | $2241.4 | $2069.9 | $844.8 | $1225.1 |

---

The increase in the gross carrying amount of intangible assets in 2025 was primarily driven by certain customer relationships, proprietary technology and acquired backlog recognized as a result of the acquisition accounting associated with the 2025 Acquisitions, in particular, the Andrew and Trexon acquisitions. Amortization expense for the years ended December 31, 2025, 2024 and 2023 was approximately $192.0, $154.7 and $86.0, respectively, which included the amortization of acquired backlog of $28.2, $55.0 and $12.4, respectively, resulting from acquisitions in each respective year. The amortization of acquired backlog in 2025 primarily resulted from the Andrew and Trexon acquisitions. The amortization of acquired backlog in 2024 resulted from the CIT acquisition. As of December 31, 2025, amortization expense relating to the Company's current intangible assets estimated for each of the next five fiscal years is approximately $207.0 in 2026, $176.7 in 2027, $169.5 in 2028, $158.6 in 2029, and $155.9 in 2030.

***Note 13—Reportable Business Segments and International Operations***

The Company aligns its businesses into three reportable business segments: *(i) Communications Solutions, (ii) Harsh Environment Solutions* and *(iii) Interconnect and Sensor Systems*. This segment structure reflects (i) the manner in which the Chief Operating Decision Maker ("CODM"), who is the Company's Chief Executive Officer, regularly assesses information for decision-making purposes, including the allocation of resources, and (ii) how the Company operates its businesses, assesses performance, and communicates results and strategy, among other items, to the Board and its stockholders. The Company has three segment managers to lead their respective reportable business segments, each reporting directly to the Chief Executive Officer. The Company organizes its reportable business segments based on the manner in which management evaluates the performance of the Company, combined with the nature of the individual business activities and the product-based solutions offered.

The Company aligns its businesses into the following three reportable business segments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Communications Solutions* – the Communications Solutions segment designs, manufactures and markets a broad range of connector and interconnect systems, including high speed, radio frequency, power, fiber optic and other interconnect products; coaxial, fiber optic and high-speed cable; antennas; and other products for use in the information technology and data communications, mobile devices, industrial, communications networks, automotive, commercial aerospace and defense end markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Harsh Environment Solutions* – the Harsh Environment Solutions segment designs, manufactures and markets a broad range of ruggedized interconnect products, including connectors and interconnect systems, specialty cable, printed circuits and printed circuit assemblies and other products for use in the industrial, defense, commercial aerospace, automotive, communications networks and information technology and data communications end markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Interconnect and Sensor Systems* – the Interconnect and Sensor Systems segment designs, manufactures and markets a broad range of sensors, sensor-based systems, connectors and value-add interconnect systems used in the automotive, industrial, information technology and data communications, communications networks, defense and commercial aerospace end markets.

[**Table of Contents**](#Toc_fix)

The accounting policies of the segments are the same as those for the Company as a whole, as described in Note 1 herein. The Company's CODM assesses each segment's performance and allocates resources to each of them based on a single measure of profit and loss, which is operating income as adjusted for certain corporate and other related items and before interest, stock-based compensation expense, income taxes, amortization related to certain intangible assets and other non-cash purchase accounting costs, and nonrecurring gains and losses, as outlined in the table below (we refer to this measure as segment operating income). Intersegment net sales and operating expenses have been eliminated in the computation of consolidated net sales and operating income.

The CODM considers budget-to-actual variances in net sales and segment operating income on a quarterly basis and uses that information when making decisions about the allocation of operating and capital resources to each segment. Other than segment operating expenses (which is easily computable from the difference between net sales and segment operating income), our CODM is not regularly provided disaggregated segment level expense information as such information is not used in our CODM's decision-making related to the allocation of operating and capital resources to our segments. The Company also incurs general corporate expenses and costs which are not allocated to the reportable business segments but have been included in "Corporate / Other" in the following tables for reconciliation purposes. Assets are reviewed by the CODM on a consolidated basis and therefore are not presented by reportable business segment.

The following tables (i) summarize, by segment, total sales, intersegment sales and external net sales and (ii) reconcile each segment's external net sales to their respective segment operating income, including segment operating expenses, for each of the years ended December 31, 2025, 2024 and 2023:

Net sales by geographic area are based on the customer location to which the product is shipped. No single customer accounted for 10% or more of the Company's net sales during the years ended December 31, 2025, 2024 and 2023. As the Company is not organized by product or group of products, it is impracticable to disclose net sales by product or group of products. For further discussion related to the Company's policies surrounding revenue recognition, refer to Note 1 herein.

***Note 14—Commitments and Contingencies***

The Company is party to a number of legal and/or regulatory actions arising out of the normal course of its business. The Company records a loss contingency liability when, in the opinion of management after seeking legal advice, a loss is considered probable and the amount can be reasonably estimated. Based on information currently available and management's evaluation of such information, the Company does not believe that the resolution of any existing legal or regulatory action is expected to have a material adverse effect on the Company's financial condition, results of operations or cash flows. The Company's legal costs associated with defending itself are recorded to expense as incurred.

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.

The Company also has purchase obligations related to commitments to purchase certain goods and services. At December 31, 2025, the Company had purchase commitments of $2,006.9 in 2026, $72.1 in 2027 and 2028, combined, and $4.2 beyond 2028.

***Note 15—Subsequent Events***

The CommScope business adds significant fiber optic interconnect capabilities for the IT datacom and communications networks markets as well as a diverse range of industrial interconnect products for the building infrastructure connectivity market. CommScope will be included in the Communications Solutions segment. The Company has commenced the analysis of the purchase price allocation of the fair value of assets acquired and liabilities assumed as part of the acquisition accounting associated with the acquisition. Preliminary data and valuations related to the acquisition are incomplete. As a result, the Company is unable to disclose preliminary values related to such information.

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

None.

**Item 9A. Controls and Procedures**

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of December 31, 2025. These disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on their evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2025.

There has been no change in our internal control over financial reporting during the Company's most recent fiscal quarter ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**Management Report on Internal Control**

Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America. Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Management is responsible for establishing and maintaining adequate internal control over financial reporting of Amphenol Corporation and its subsidiaries (the "Company"), as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the Company conducted an evaluation of the effectiveness of the internal control over financial reporting based on criteria established in the *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that the Company's internal control over financial reporting was effective as of December 31, 2025.

Deloitte & Touche LLP, an independent registered public accounting firm, has audited the Company's internal control over financial reporting as of December 31, 2025 in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB). Those standards require that Deloitte & Touche LLP plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Deloitte & Touche LLP has issued an attestation report on the Company's internal control over financial reporting as of December 31, 2025, which is included in Item 8 of this Annual Report.

**Dividends**

Subject to the rights of holders of outstanding shares of preferred stock, if any, holders of the Class A Common Stock are entitled to participate in dividends as and when declared by the board of directors out of funds legally available therefor. The Company's unsecured credit facility contains financial covenants and restrictions, some of which may limit the Company's ability to pay dividends, and any future indebtedness that the Company may incur could limit its ability to pay dividends.

**Certain Anti-Takeover Matters**

*Advance Notice Requirements*

The Company's By-laws establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of stockholders, including procedures related to the use of universal proxy cards in accordance with Rule 14a-19 of the Securities Exchange Act of 1934, as amended. These procedures provide that notice of such stockholder proposals must be timely given in writing to the Secretary of the Company prior to the meeting at which the action is to be taken. The notice must contain certain information specified in the Company's By-laws. If a stockholder fails to follow the procedures in the Company's By-laws, the stockholder's nomination or proposal will be ineligible and will not be voted on by stockholders.

*Additional Authorized Shares of Capital Stock.* 

The additional shares of authorized common stock available for issuance under our Certificate of Incorporation could be issued at such times, under such circumstances and with such terms and conditions as to impede a change in control.

*Delaware General Corporation Law Section 203*

As a corporation organized under the laws of the State of Delaware, the Company is subject to Section 203 of the DGCL which restricts certain "business combinations" between the Company and an "interested stockholder" or that stockholder's affiliates or associates for a period of three years following the date on which the stockholder becomes an "interested stockholder." The restrictions do not apply if:

● prior to an interested stockholder becoming such, the board of directors of the Company approves either the business combination or the transaction in which the stockholder becomes an interested stockholder;

● upon consummation of the transaction in which the stockholder becomes an interested stockholder, the interested stockholder owns at least 85% of the outstanding voting stock of the Company at the time the transaction commenced, subject to certain exceptions; or

● on or after the date an interested stockholder becomes such, the business combination is both approved by the board of directors of the Company and authorized at an annual or special meeting of the Company's stockholders (and not by written consent) by the affirmative vote of at least 66 2/3% of the outstanding voting stock not owned by the interested stockholder.

For purposes of Section 203 of the DGCL, a "business combination" includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An "interested stockholder" is a person who, together with affiliates and associates, owns (or within three years did own) 15% or more of a corporation's voting stock. The statute could have the effect of delaying, deferring or preventing a change in control of the Company's or reducing the price that some investors might be willing to pay in the future for the Class A Common Stock.

**Transfer Agent and Registrar**

The transfer agent and registrar for the Company's Class A Common Stock is Computershare Trust Company, N.A.

**DESCRIPTION OF 3.125% SENIOR NOTES DUE 2032**

The following description of the Company's 3.125% Senior Notes due 2032 (the "notes") is a summary and does not purport to be complete. This description is qualified in its entirety by reference to the indenture, dated as of March 16, 2023, between the Company and U.S. Bank Trust Company, National Association, as trustee (as such indenture has been and may be amended from time to time, the "indenture") and the Officer's Certificate, dated June 16, 2025, filed as Exhibit 4.2 to the Company's Current Report on Form 8-K, which was filed with the Securities and Exchange Commission (the "SEC") on June 16, 2025 (the "Officer's Certificate). The notes are listed on the New York Stock Exchange. Unless otherwise specified, all capitalized and undefined terms in this section have the meanings specified in the indenture and in the Officer's Certificate. References in this section to "Amphenol," the "Company," "us," "we" and "our" are solely to Amphenol Corporation and not to any of its subsidiaries, unless the context requires otherwise.

The notes constitute a series of "senior debt securities" under the indenture. The terms of the notes include those terms expressly set forth in the indenture, the Officer's Certificate and those made part of the indenture by the Trust Indenture Act of 1939, as amended. Amphenol may, without notice to or consent of holders, issue an unlimited principal amount of additional notes having identical terms (other than issue date, issue price and, in some cases, the first interest payment date), subject to compliance with the indenture covenants at the time of issuance. Any such additional notes will be part of the same series as the notes, will vote together, and, if not fungible for U.S. federal income tax purposes, will be issued under a separate CUSIP/ISIN/Common Code and, for so long as required by applicable law or clearing system procedures, may be represented by separate global notes.

**General**

The notes were issued in an initial aggregate principal amount of €600,000,000, however, we may issue additional notes at a later time that will be part of the same issue as the series of notes. The notes are issued only in fully registered form, without coupons, in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. The notes are represented by one or more global securities deposited with, or on behalf of, a common depositary for Euroclear and Clearstream. The notes will mature on June 16, 2032 unless earlier redeemed by us, and upon surrender will be repaid at 100% of the principal amount thereof.

**Interest**

Principal of and premium, if any, and interest on the notes are payable to the registered holder in euros in immediately available funds. The notes bear interest at the rate of 3.125% per annum, from June 16, 2025, or from the most recent interest payment date on which interest has been paid or provided for. Interest on the notes is computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes, to but excluding the next scheduled interest payment date. This payment convention is referred to as Actual/Actual (ICMA) as defined in the rulebook of the International Capital Market Association.

------

Payments on the notes are made through the principal paying agent (as defined herein under the heading "- Paying Agent and Registrar"). Payments on the notes are made at the specified office or agency of the principal paying agent. We may also choose to pay interest by mailing checks or making wire transfers. We may also arrange for additional paying agent offices and may change these offices.

**Payment on the Notes**

Initial holders were required to pay for the notes in euro, and all payments of interest and principal, including payments made upon any redemption of the notes and any payment of additional amounts, will be payable in euro. However, if the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control, or if the euro is no longer being used by the then-member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments with respect to the notes will be made in U.S. dollars until the euro is again available to us or so used.

**Paying Agent and Registrar**

U.S. Bank Europe DAC, UK Branch, acts as principal paying agent for the notes (the "principal paying agent"). U.S. Bank Trust Company, National Association, will initially act as transfer agent and security registrar. Upon notice to the trustee, we may change any paying agent or security registrar, and we or any of our subsidiaries may act as paying agent or security registrar.

**Optional Redemption**

Prior to the Par Call Date (as defined below), we may redeem the notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on an annual (Actual/Actual (ICMA)) basis at a rate equal to the comparable government bond rate (as defined below), plus 15 basis points, less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date. On or after the Par Call Date, we may redeem the notes, at our option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

For purposes of this section, the following terms have the following meanings:

● "Par Call Date" means March 16, 2032 (three months prior to the maturity date).

● "comparable government bond" means, with respect to the notes to be redeemed prior to the applicable Par Call Date in relation to any comparable government bond rate calculation, at the discretion of an independent investment banking institution of international standing selected by us (an "independent investment banker"), a bond that is a direct obligation of the Federal Republic of Germany (a "German government bond") whose maturity is closest to the Par Call Date of the notes to be redeemed, or if such independent investment banker in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment banker may, with the advice of three brokers of, and/or market makers in, German government bonds selected by us, determine to be appropriate for determining the comparable government bond rate.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

● "comparable government bond rate" means the yield (rounded to three decimal places, with 0.0005 being rounded upwards) of the comparable government bond on the third Business Day prior to the date fixed for redemption, calculated on the basis of the middle market price of such comparable government bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment banker selected by us and calculated in accordance with generally accepted market practice at the time.

If fewer than all of the notes are to be redeemed at any time, the principal paying agent will select the notes to be redeemed in accordance with the rules of the New York Stock Exchange; provided that no such partial redemption shall reduce the portion of the principal amount of a note not redeemed to less than €100,000. Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary's procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions thereof called for redemption. Except as described above, the notes will not be redeemable by us prior to maturity and will not be entitled to the benefit of any sinking fund. We may acquire notes by means other than a redemption, whether by tender offer, open-market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the indenture.

**Redemption Upon Changes in Withholding Taxes**

If (a) as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein having power to tax) (a "Relevant Taxing Jurisdiction"), or any change in, or amendment to, the official position regarding the application or interpretation of such laws, regulations or rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), we become or will become obligated to pay additional amounts as described under 'Payment of Additional Amounts" or (b) any act is taken by a Relevant Taxing Jurisdiction that results in a substantial probability that we will be required to pay such additional amounts, then we may, at our option, redeem the notes, as a whole but not in part, upon not less than 15 days' nor more than 60 days' published notice, at 100% of their principal amount, together with interest accrued thereon to, but not including, the date fixed for redemption; provided that we determine, in our business judgment, that the obligation to pay such additional amounts cannot be avoided by the use of reasonable measures available to us (which does not include substitution of the obligor under the notes). No such redemption may be made unless we have received an opinion of independent counsel to the effect that as a result of such change or amendment we will, or that an act taken by a Relevant Taxing Jurisdiction has resulted in a substantial probability that we will, be required to pay such additional amounts described under "Payment of Additional Amounts", and we shall have delivered to the trustee an officer's certificate stating that, based on such opinion, we are entitled to redeem the notes pursuant to their terms.

**Payment of Additional Amounts**

All payments of principal, premium, if any, and interest on the notes will be made free and clear of and without withholding or deduction for or on account of any present or future tax, assessment or other governmental charge ("Taxes") imposed by any Relevant Taxing Jurisdiction, unless such withholding is required by law or the official interpretation or administration thereof. If such withholding is required, we will, subject to the exceptions and limitations set forth in the Officer's Certificate, pay such additional amounts as are necessary so that the net payment of the principal of, premium, if any, and interest on the notes to a beneficial owner of the notes who is not a U.S. person, after the withholding of such Taxes (including any withholding on the payment of such additional amounts), will not be less than the amount

------

provided to be then due and payable, subject to the exceptions and limitations set forth in the Officer's Certificate. Each holder entitled to any such additional amounts shall cooperate with us and the trustee in providing any information or documentation reasonably requested by us or the trustee to confirm the identity and/or tax status of such holder and any affected beneficial owner (to the extent necessary to establish such holder's entitlement to such additional amounts) and to assist us or the trustee in determining the applicable withholding tax rate and the amount of additional amounts payable.

**Ranking**

The notes are senior unsecured and unsubordinated indebtedness and rank equally with all of our existing and future senior unsecured and unsubordinated indebtedness, including our other outstanding notes, our guarantees of certain subsidiary-issued euro notes and borrowings under our revolving credit facility. However, the notes are structurally subordinated to the indebtedness of our subsidiaries and effectively subordinated to any future secured indebtedness to the extent of the value of the assets securing such indebtedness. None of our subsidiaries guarantee the notes, and claims of holders of the notes will be effectively subordinated to the claims of creditors of our subsidiaries.

**Change of Control**

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem all of the notes as described under "Optional Redemption," each holder will have the right to require us to repurchase all or any part (equal to €100,000 and integral multiples of €1,000 in excess thereof) of such holder's notes pursuant to the offer described below (the "Change of Control Offer") at a purchase price in cash equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date).

Within 30 days following any Change of Control Repurchase Event, or, at our option, prior to any Change of Control but after the public announcement of the pending Change of Control, we will send a notice to each holder (with a copy to the trustee) stating: (i) that such Change of Control Repurchase Event has occurred or is pending and that such holder has the right to require us to repurchase such holder's notes at a purchase price in cash equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of holders of record on the relevant interest record date to receive interest due on the relevant interest payment date) (the "Change of Control Payment"); (ii) if such notice is mailed prior to the date of consummation of the Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date; (iii) the date of repurchase (which shall be no earlier than 30 days nor later than 60 days from the date the Change of Control Offer is mailed) (the "Change of Control Payment Date"); and (iv) the procedures determined by us, consistent with the indenture, that a holder must follow in order to have its notes repurchased. On the Change of Control Payment Date, we will accept for payment all notes or portions properly tendered, deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions so tendered, and deliver to the trustee the notes so accepted together with an officer's certificate stating the aggregate principal amount being repurchased and any executed new note(s) for unpurchased portions.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the person in whose name a note is registered on such record date, and no additional interest will be payable to tendering holders.

We will not be required to make the Change of Control Offer upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the indenture and repurchases all notes validly tendered and not withdrawn. We will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other applicable

------

securities laws or regulations; to the extent any such laws or regulations conflict with the indenture's offer mechanics, we will comply with those laws and regulations and will not be deemed in breach of the note terms by virtue of such compliance.

Our ability to repurchase notes pursuant to the Change of Control Offer may be limited by a number of factors. Certain events that may constitute a change of control under our other senior indebtedness and indebtedness of our subsidiaries and cause a default under the agreements related to such indebtedness may not constitute a Change of Control Repurchase Event under the indenture. Our revolving credit facility provides that the occurrence of certain change of control events would constitute a default thereunder. Future indebtedness of ours and our subsidiaries may also contain prohibitions of certain events that would constitute a Change of Control Repurchase Event or require such indebtedness to be repurchased upon a Change of Control Repurchase Event. Moreover, any exercise by the holders of our outstanding senior notes of their right to require us to repurchase their notes could cause a default under such indebtedness, even if a Change of Control Repurchase Event itself does not, due to the financial effect of such repurchases on us. Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources.

Even if sufficient funds were otherwise available, the terms of our future indebtedness may prohibit our prepayment of the notes before their scheduled maturity. Consequently, if we are not able to prepay our senior indebtedness and any such other indebtedness containing similar restrictions or obtain requisite consents, we will not be able to fulfill our repurchase obligations if holders of notes exercise their repurchase rights following a Change of Control Repurchase Event, resulting in a default under the indenture. A default under the indenture will result in a cross-default under our other senior indebtedness, including under our revolving credit facility.

The Change of Control Repurchase Event provisions described above may deter certain mergers, tender offers and other takeover attempts involving us by increasing the capital required to effectuate such transactions. The definition of "Change of Control" below includes a disposition of all or substantially all of our property and assets and our subsidiaries taken as a whole to any person. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of "all or substantially all" of the property or assets of a person. As a result, it may be unclear as to whether or not a Change of Control, and thus a Change of Control Repurchase Event, has occurred and whether or not a holder of notes may require us to make an offer to repurchase the notes as described above. The provisions under the indenture relative to our obligation to make an offer to repurchase the notes as a result of a Change of Control Repurchase Event may be waived or modified with the written consent of the holders of a majority in principal amount of the outstanding notes.

For purposes of this section, the following terms have the following meanings:

● "Change of Control" means: (a) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any "person" (as such term is used in Sections 13(d)(3) of the Exchange Act) becomes the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act, except that such person shall be deemed to have "beneficial ownership" of all shares that any such person has the right to acquire, whether such right is exercisable immediately or only after the passage of time), directly or indirectly, of more than 50% of the total voting power of our Voting Stock (or our successor by merger, consolidation or purchase of all or substantially all of our assets) (for the purposes of this definition, such person shall be deemed to beneficially own any of our Voting Stock held by a parent entity, if such person "beneficially owns" (as defined above), directly or indirectly, more

------

than a majority of the voting power of the Voting Stock of such parent entity); or (b) we consolidate with, or merge with or into, any person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding Voting Stock or outstanding Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of our Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction; or (c) the first day on which a majority of the members of our board of directors are not Continuing Directors; or (d) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our assets and the assets of the subsidiaries taken as a whole to any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than to us or one of our subsidiaries; or (e) the adoption by our stockholders of a plan or proposal for our liquidation or dissolution.

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (a) we become a direct or indirect wholly owned subsidiary of a holding company and (b) immediately following that transaction, (1) the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (2) no person or group is the beneficial owner, directly or indirectly, of more than a majority of the total voting power of the Voting Stock of the holding company.

● "Change of Control Repurchase Event" means the occurrence of both a Change of Control and a Rating Decline with respect to such Change of Control.

Notwithstanding anything in this section, no Change of Control Repurchase Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

● "Continuing Directors" means, as of any date of determination, any member of our board of directors who (a) was a member of our board of directors on the date of issuance of the notes or (b) was nominated for election or elected to our board of directors with the approval of a majority of the Continuing Directors who were members of our board of directors at the time of such nomination or election.

● "Investment Grade" means BBB- or higher by S&P and Baa3 or higher by Moody's, or the equivalent of such ratings by S&P or Moody's or, if either S&P or Moody's shall not make a rating on the notes publicly available, another Rating Agency.

● "Moody's" means Moody's Investors Service Inc. and its successors.

● "Rating Agency" means each of S&P and Moody's or, to the extent S&P or Moody's or both do not make a rating on the notes publicly available, a "nationally recognized statistical rating organization" (within the meaning of Section 3(a)(62) under the Exchange Act) or "organizations," as the case may be, selected by us (as certified by a resolution of our board of directors), which shall be substituted for S&P or Moody's, or both, as the case may be.

● "Rating Decline" means, with respect to a Change of Control, the notes cease to be rated Investment Grade by each Rating Agency on any date during the period ("Trigger Period") from

------

the date of the public notice of an arrangement that could result in such Change of Control until 60 days following the consummation of such Change of Control (which Trigger Period will be extended for so long as the rating on the notes is under publicly announced consideration for a possible downgrade by either of the Rating Agencies).

● "S&P" means S&P Global Ratings, a division of S&P Global Inc., and its successors.

● "Voting Stock" of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors, managers or trustees, as applicable, of such person.

**Defaults and Remedies**

***Events of Default.***

The following are "Events of Default" with respect to the notes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) default in the payment of the notes when due, continued for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) default in the payment of principal of or premium, if any, on the notes at its Maturity, including at the Stated Maturity, upon redemption or required repurchase or by declaration of acceleration or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) default in the performance or breach of any covenant or warranty of the Company in the indenture, which default continues uncured for 90 days after written notice as specified in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) a failure to make any payment at maturity (including any applicable grace period) on any of the Company's Indebtedness in excess of $50,000,000 or a default on any such Indebtedness that results in the acceleration of Indebtedness in an amount in excess of $50,000,000;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) certain events of bankruptcy, insolvency or reorganization with respect to the Company, as specified in the indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) any additional Event of Default provided with respect to notes in a Board Resolution, officer's certificate or Supplemental Indenture.

If an Event of Default (other than certain bankruptcy or insolvency events specified in (e) and (f) above) occurs and is continuing with respect to the notes, then the trustee or the holders of at least 25% in aggregate principal amount of the outstanding notes may declare the entire principal amount and accrued but unpaid interest, if any, on the notes to be due and payable immediately by written notice to the Company, and upon such declaration such amounts shall become immediately due and payable.

If an Event of Default specified in (e) or (f) above occurs, the principal (or specified amount) of and accrued but unpaid interest, if any, on the notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the trustee or any holder. The holders of a majority in principal amount of the outstanding notes may rescind and annul an acceleration and its consequences on the terms and conditions set forth in the indenture, including payment of overdue amounts and cure or waiver of defaults other than a nonpayment default due solely to such acceleration.

If a payment default occurs and continues, the Company will, upon demand of the trustee, pay to the trustee for the benefit of the holders the whole amount then due and payable, including, to the extent legally enforceable, interest on overdue principal and interest and the costs and expenses of collection; failing such payment, the Trustee may institute judicial proceedings to collect such sums and enforce any

------

related judgment against the Company or any other obligor on the notes. If an Event of Default with respect to the notes occurs and is continuing, the trustee may proceed to protect and enforce its rights and those of the holders by appropriate judicial proceedings, including specific performance, and pursue any other proper remedy, all as provided in the indenture. In any insolvency or similar proceeding, the trustee is entitled to file proofs of claim, collect and receive any moneys or property payable on such claims and distribute the same as provided in the indenture. No holder may institute any proceeding or pursue any remedy with respect to the indenture unless the holder has given notice of a continuing Event of Default, the holders of at least 25% in principal amount of the outstanding notes have requested that the trustee institute such proceedings and offered it indemnity, the trustee has failed to act for 60 days and the holders of a majority have not given an inconsistent direction; however, these limitations do not affect any holder's absolute and unconditional right to receive payment of principal and interest when due and to sue for the enforcement of such payment on or after the due dates. The rights and remedies under the indenture are cumulative, may be exercised repeatedly and the delay or omission to exercise any right does not operate as a waiver. The holders of a majority in principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for any remedy or exercising any trust or power conferred on the trustee, subject to the limitations and protections set forth in the indenture, and may waive past defaults (other than certain payment defaults and non-amendable provisions), as further provided in the indenture.

**Covenants**

***Limitation on Liens.***

So long as any notes are outstanding, the Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, issue, incur, create, assume or guarantee any Indebtedness secured by a Mortgage on any Principal Property or on any shares of Capital Stock or Indebtedness of any Restricted Subsidiary, unless the notes are equally and ratably secured with such Indebtedness (or, at the Company's option, prior thereto), subject to the customary exceptions and baskets set forth in the indenture, including but not limited to existing Mortgages, certain acquisition, construction or improvement Mortgages within 270 days, intra-group Mortgages, government-secured obligations, Nonrecourse Obligation project Mortgages, Mortgages on accounts receivable, Mortgages securing all of the Securities, and certain extensions, renewals or replacements without increase in principal. In addition, the Company and its Restricted Subsidiaries may incur Indebtedness secured by Mortgages without equally and ratably securing the notes so long as, after giving effect thereto and any concurrent retirement of debt, the aggregate amount of all such Indebtedness (excluding Mortgages permitted under specified clauses) does not exceed 15% of Consolidated Net Tangible Assets, and any Mortgage securing the Securities granted pursuant to this covenant will be automatically released upon the release of the Mortgage that gave rise to such security for the notes.

***Limitation on Sale/Leaseback Transactions.***

Neither the Company nor any Restricted Subsidiary will enter into any Sale/Leaseback Transaction with respect to any Principal Property unless, at the time thereof, it would be permitted to incur a Mortgage on such property in an amount at least equal to the Attributable Debt without equally and ratably securing the notes, or the net proceeds of the sale are at least equal to the fair market value of such property (as determined by the Board of Directors) and are applied within 180 days to the purchase, construction, development or acquisition of assets that are Principal Property or to the repayment of senior Indebtedness of the Company or any Restricted Subsidiary, subject to the exceptions set forth in the indenture and the general basket that, together with Indebtedness secured by Mortgages under the de minimis basket, may not exceed 15% of Consolidated Net Tangible Assets; a Sale/Leaseback Transaction shall not be deemed to create a Mortgage.

***Mergers, Consolidations and Transfers of Assets.***

The Company shall not consolidate with or merge into any other Person or sell, lease, convey or otherwise transfer all or substantially all of its assets to any other Person, unless the successor is a corporation organized under the laws of any U.S. state or the District of Columbia that expressly assumes the Company's obligations under the notes and the indenture, immediately after giving effect to the transaction no Event of Default (or event that would become an Event of Default) shall have occurred and be continuing, and the Company delivers an officer's certificate and opinion of counsel stating that the transaction complies with the indenture; upon such transaction, the successor will be substituted for the Company, and, except in the case of a lease, the predecessor shall be released from its obligations.

**Satisfaction and Discharge; Defeasance**

At our option, evidenced by a Board Resolution or an officer's certificate, we may, at any time with respect to the notes, elect to have either Legal Defeasance and Discharge or Covenant Defeasance applied to all outstanding notes upon compliance with the conditions set forth in Article VIII of the indenture.

Upon our exercise of the Legal Defeasance and Discharge option, we will be deemed to have been discharged from our obligations with respect to all outstanding notes as of the date the conditions in Section 8.4 of the indenture are satisfied (such discharge, "Legal Defeasance"), and the trustee, on our written demand and at our expense, will execute proper instruments acknowledging the same. Legal Defeasance means we shall be deemed to have paid and discharged all obligations relating to the notes and the indenture and cured all then existing Events of Default, except that the following shall survive until otherwise terminated or discharged: (a) the rights of holders of outstanding notes to receive payments of principal and interest when due and on any redemption date solely out of the trust created pursuant to the indenture; (b) our obligations with respect to issuing temporary securities, or, where relevant, registration of securities, replacement of mutilated, destroyed, lost or stolen securities, and the maintenance of an office or agency for payment and money for payments held in trust; (c) the rights, powers, trusts, duties and immunities of the trustee, and our obligations in connection therewith, including our obligations to the trustee under Section 7.7 of the indenture; and (d) Article VIII of the indenture. We may exercise Legal Defeasance notwithstanding a prior exercise of Covenant Defeasance with respect to the notes. Following Legal Defeasance, payment of the notes may not be accelerated because of an Event of Default.

Upon our exercise of the Covenant Defeasance option, we will be released from our obligations under the covenants contained in Sections 2.2(s), 4.2, 4.3, 4.4, 4.5 and 5.1 of the indenture with respect to the outstanding notes, and from any additional covenants contained in the notes, any Supplemental Indenture or officer's certificate, on and after the date the conditions in Section 8.4 of the indenture are satisfied ("Covenant Defeasance"), and the notes shall thereafter be deemed not "outstanding" for purposes of any direction, waiver, consent or declaration or act of holders (and the consequences thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes (it being understood that such notes shall not be deemed outstanding for accounting purposes). Covenant Defeasance means that, with respect to the outstanding notes appertaining thereto, we may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere in the indenture to any such covenant or by reason of any reference in any such covenant to any other provision in the indenture or in any other document, but, except as specified above, the remainder of the indenture and the notes shall be unaffected. Following Covenant Defeasance, payment of the notes may not be accelerated because of an Event of Default pursuant to Section 6.1(c) of the indenture (except for a default with respect to Section 5.1), 6.1(d) or 6.1(g). of the indenture).

------

The following are conditions to the application of either Legal Defeasance or Covenant Defeasance: (a) we must irrevocably deposit, or cause to be irrevocably deposited, with the trustee, in trust for the benefit of the holders, cash in the currency or currency unit in which the notes are payable, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of an internationally recognized firm of independent public accountants, to pay the principal of and interest, if any, due on the notes at their maturity or on the applicable redemption date; (b) in the case of Legal Defeasance, we shall have delivered to the trustee an Opinion of Counsel in the United States reasonably acceptable to the trustee confirming that, subject to customary assumptions and exclusions, we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling or, since the date of issuance of the notes, there has been a change in applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel confirming that, subject to customary assumptions and exclusions, the beneficial owners of the notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if Legal Defeasance had not occurred; (c) in the case of Covenant Defeasance, we shall have delivered to the trustee an Opinion of Counsel in the United States reasonably acceptable to the trustee confirming that, subject to customary assumptions and exclusions, the beneficial owners of the notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if Covenant Defeasance had not occurred; (d) no Event of Default, or event that with notice or lapse of time, or both, would become an Event of Default with respect to the notes, shall have occurred and be continuing on the date of deposit and no Event of Default under Section 6.1(e) or 6.1(f) of the indenture shall have occurred and be continuing on the 91st day after such date; (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument to which we are a party or by which we are bound; and (f) we shall have delivered to the trustee an officer's certificate and an Opinion of Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent relating to the Legal Defeasance or Covenant Defeasance, as the case may be, have been complied with.

The indenture will, upon our request, be discharged and cease to be of further effect as to all of the notes when either: (a) all notes theretofore authenticated and delivered (except (i) lost, stolen or destroyed notes that have been replaced or paid as provided in Section 2.8 of the indenture and (ii) notes for whose payment money has theretofore been deposited in trust and thereafter repaid to us or discharged from such trust as provided in Section 8.9 of the indenture) have been delivered to the trustee for cancellation; or (b) (i) all notes not theretofore delivered to the trustee for cancellation are due and payable by their terms within one year or have become due and payable by reason of a notice of redemption, and we have irrevocably deposited with the trustee as trust funds in trust an amount of cash in any combination of currency or currency unit in which the notes are payable, U.S. Government Obligations, or a combination thereof in such amounts as will be sufficient to pay and discharge the entire indebtedness on the notes for principal and accrued but unpaid interest, if any, to their maturity or the date of redemption, as the case may be, (ii) we have paid all sums payable by us under the indenture and (iii) we have delivered irrevocable instructions to the trustee to apply the deposited money toward such payments at Stated Maturity or the redemption date, as the case may be. In either case, we must deliver an officer's certificate and an Opinion of Counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding satisfaction and discharge of the indenture and the notes, the respective obligations of us and the trustee under Sections 2.3, 2.5, 2.6, 2.7, 2.8, 2.12, 6.8, 8.7, 8.8, 8.9 and 8.10 and Article VII of the indenture will survive with respect to the notes until they are no longer outstanding, and thereafter the obligations under Sections 8.7, 8.8, 8.9 and 8.10 of the indenture shall survive. Nothing in Article VIII

------

of the indenture abrogates any of the trustee's obligations or duties under the indenture. After (a) the conditions of Section 8.4 or 8.5 of the indenture have been satisfied with respect to the notes, (b) we have paid or caused to be paid all other sums payable by us, and (c) we have delivered to the trustee an officer's certificate and an Opinion of Counsel stating that all applicable conditions precedent have been complied with, the trustee, upon our written request, shall acknowledge in writing the discharge of all our obligations under the indenture except for the surviving obligations specified in Article VIII of the indenture.

All money and U.S. Government Obligations deposited with the trustee pursuant to Section 8.4 or 8.5 of the indenture in respect of the notes will be held in trust and applied, in accordance with the provisions of the notes and the indenture, to the payment, either directly or through any paying agent as the trustee may determine, to holders of all sums due and to become due thereon for principal and interest, if any; such money need not be segregated from other funds except to the extent required by law. We will pay and indemnify the trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited, or the principal and interest received thereon, other than any such tax, fee or other charge that by law is for the account of the holders.

The trustee and any paying agent shall promptly pay or return to us upon our order any cash or U.S. Government Obligations held by them at any time that are not required for the payment of principal and interest on the notes for which cash or U.S. Government Obligations have been deposited pursuant to Section 8.4 or 8.5 of the indenture. Any money deposited with the trustee or any paying agent, or then held by us, in trust for the payment of principal or interest on the notes and remaining unclaimed for two years after such principal or interest has become due and payable shall, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law, be paid to us on our request or, if then held by us, be discharged from such trusts; the holder of such note shall thereafter, as an unsecured general creditor, look only to us for payment, and all liability of the trustee or such paying agent with respect to such trust money, and all liability of us as trustee thereof, shall thereupon cease; provided that the trustee or paying agent, before making any such repayment, may give written notice to the holder that such money remains unclaimed and will be repaid to us after a date specified therein, not less than 30 days from the date of such notice, unless otherwise required by mandatory provisions of applicable escheat or abandoned or unclaimed property law.

If the trustee or paying agent is unable to apply any cash or U.S. Government Obligations in accordance with Section 8.2, 8.3, 8.4 or 8.5 of the indenture by reason of any legal proceeding or any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, our obligations under the indenture and the notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, 8.3, 8.4 or 8.5 of the indenture until such time as the trustee or paying agent is permitted to apply all such cash or U.S. Government Obligations in accordance with such sections; provided that if we have made any payment of principal or interest on any notes because of such reinstatement, we shall be subrogated to the rights of the holders of such notes to receive such payment from the cash or U.S. Government Obligations held by the trustee or paying agent.

**Amendments and Waivers**

We and the trustee may amend or supplement the indenture or the notes without the consent of any holder in order to: cure, correct or supplement any ambiguity, omission, defect or inconsistency; comply with Article V of the indenture (including to provide for a successor obligor); provide for uncertificated notes in addition to or in place of certificated notes; add guarantees or collateral security with respect to the notes; add covenants for the benefit of holders or surrender any right or power conferred upon us; make any change that does not adversely affect the rights of any holder in any material respect; provide for the issuance of and establish the form and terms and conditions of notes of any series; change or

------

eliminate provisions of the indenture so long as no security outstanding of any previously created series is adversely affected; evidence and provide for the acceptance of appointment by a successor trustee and make related changes to facilitate administration of the trusts by more than one trustee; or comply with SEC requirements to effect or maintain qualification of the indenture under the Trust Indenture Act.

We and the trustee may enter into a Supplemental Indenture with the written consent of the holders of at least a majority in principal amount of the outstanding notes affected by such Supplemental Indenture (including consents obtained in connection with a tender offer or exchange offer for the notes), for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of any Supplemental Indenture or of modifying in any manner the rights of the holders of the notes. Except as provided in Section 6.13 of the indenture, the holders of at least a majority in principal amount of the outstanding notes by notice to the trustee (including consents obtained in connection with a tender offer or exchange offer for the notes) may waive any past Default or compliance by us with any provision of the indenture or the notes. It shall not be necessary for the consent of the holders of the notes to approve the particular form of any proposed Supplemental Indenture or waiver, but it shall be sufficient if such consent approves the substance thereof. After a Supplemental Indenture or waiver becomes effective, we shall mail to the holders of notes affected thereby a notice briefly describing such Supplemental Indenture or waiver. Any failure by us to mail or publish such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such Supplemental Indenture or waiver.

Without the consent of each holder affected, an amendment or waiver may not: (a) reduce the amount of notes whose holders must consent to an amendment, supplement or waiver; (b) reduce the rate of or extend the time for payment of interest (including default interest) on the notes; (c) reduce the principal of, or premium, if any, on the notes or change the notes' maturity, including the Stated Maturity or the date of redemption or required repurchase thereof; (d) reduce the principal amount of Discount Securities payable upon acceleration of the maturity thereof; (e) make the principal of or interest, if any, on the notes payable in any currency other than that stated in the note; (f) impair the right of any holder of the notes to receive payment of principal of and interest on the notes on or after the due dates for the payment of such principal or interest or to institute suit for the enforcement of any payment on or with respect to such notes; (g) make any changes that would affect the ranking for the notes in a manner adverse to the holders; or (h) make any change in Section 6.8, 6.13 or 9.3 of the indenture.

**Book-Entry and Settlement**

The notes are represented by one or more global notes deposited with or on behalf of a common depositary for Euroclear and Clearstream, and beneficial interests are held through participants in those systems; certificated notes will be issued only in limited circumstances. Transfers of beneficial interests in the global notes will be effected through the procedures of Euroclear and Clearstream and their participants.

**Reporting**

For so long as any notes are outstanding, Amphenol will file with the trustee, within 15 days after filing with the SEC, copies of annual reports and the information, documents and other reports that Amphenol is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, or, if Amphenol is not required to file such reports, Amphenol will file with the trustee and the SEC such information as may be required pursuant to Section 13 of the Exchange Act for a security listed on a national securities exchange. Amphenol will be deemed to have furnished such information to holders if filed with the SEC via EDGAR and publicly available thereon.

**Notices** 

------

Notices to holders will be sent by Amphenol or its designee and will be deemed given on the date of sending; so long as the notes are represented by a global security deposited with the common depositary for Euroclear and Clearstream, notices may be given by delivery to Euroclear and Clearstream and will be deemed given on the date of delivery. The trustee will transmit notices to registered holders' last known addresses as they appear in the security register, and holders will not receive notices directly from Amphenol unless the notes are issued in certificated form.

**Additional Information**

The indenture contains additional provisions applicable to the notes, including transfer and exchange mechanics, the governing law of the indenture and the notes, and trustee and settlement provisions.

**The Trustee**

U.S. Bank Trust Company, National Association, serves as trustee under the indenture for the notes.

**Exhibit 10.26**

**2026**

**AMPHENOL MANAGEMENT INCENTIVE PLAN**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. **Purpose** 

The purpose of the 2026 Management Incentive Plan (the "2026 Incentive Plan") is to reward eligible key management personnel of Amphenol Corporation and affiliated operations with performance-based cash bonus payments provided certain goals are achieved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;II. **Eligibility** 

Generally, participation includes senior management positions, corporate staff managers, general managers and their designated direct reports. Participation and target bonuses are as approved by the Compensation Committee of the Board of Directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;III. **Plan Components** 

Payments under the 2026 Incentive Plan are based primarily on performance against quantitative measures established at the beginning of each year. In addition, consideration will be given, when appropriate, to certain qualitative factors considered relevant or appropriate as determined by the Compensation Committee.

The quantitative portion of the 2026 Incentive Plan is contingent upon achievement by the Company, a Division, a Group, a business unit and/or an individual (each referred to as a "responsibility unit"), as applicable, of performance targets and/or goals. For 2026, quantitative performance criteria are based primarily on sales and income growth in 2026 over 2025 and additionally, for some responsibility units, actual performance in 2026 as compared to 2026 budget.

Performance based payments pursuant to the 2026 Incentive Plan may be adjusted if unusual and unanticipated market conditions materially impact a responsibility unit's growth and/or performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IV. **Administration** 

● Payments are based upon average base salary during the 2026 Incentive Plan year (new hires will be prorated accordingly if hired after February 1, 2026). Targets and payments may be adjusted for special situations (for example, the participant moves to a new position during the year).

● The maximum allowable payout under the 2026 Incentive Plan is 2x the target bonus as applied to average base salary.

● Participation in MIP replaces any and all prior bonus plans for which a participant may have been eligible.

● The Committee may adjust the payout of any or all participants in consideration of (i) whether the payout to all participants as a percentage of the Company's operating income falls within certain historical parameters, (ii) how the multiplier for the current year compares with the prior year, (iii) reasonableness and consistency and (iv) internal pay equity.

● To be eligible for the bonus payment, a participant must be an active employee on the payroll and in good standing as of December 31, 2026. Exceptions must be recommended by the CEO and be approved by the Compensation Committee.

● All payments are subject to the approval of the Compensation Committee.

● Payments will not be made later than March 15, 2027.

● The Compensation Committee will interpret and administer the 2026 Incentive Plan at its discretion.

● The 2026 Incentive Plan is intended to be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations and other applicable guidance issued thereunder ("Section 409A") or if not exempt, to satisfy the requirements of Section 409A, and the provisions of the 2026 Incentive Plan shall be construed in a manner consistent therewith.
