Insights

Proxy combines strong 2025 performance with standard governance and pay structures.

Amphenol reports record 2025 performance: sales of $23.1 billion were up 52% in U.S. dollars and 38% organically, with GAAP and Adjusted Diluted EPS of $3.34 up more than 70% versus 2024. Operating margin reached 25.4%, adjusted to 26.2%, and free cash flow was $4.4 billion.

The proxy details an annual election of eight directors, most of whom are independent, and a broad committee structure overseeing audit, compensation, finance, and sustainability topics. Long-term shareholder alignment is emphasized through stock ownership guidelines, a clawback policy, and heavy use of stock options and performance-linked cash incentives.

Compensation for 2025 was highly performance-based: the CEO’s fixed elements were about 9% of total pay, with roughly 91% in at-risk incentives. Other named executive officers had about 85% of pay at risk. Over ten years, management reports net sales growth of 315%, Adjusted Diluted EPS growth of 457%, and approximately 27% compound annual shareholder return through December 31, 2025.

Key Terms

6 terms

Adjusted Diluted EPS financial

"Adjusted Diluted EPS of $3.34, up 77% compared to prior year"

Adjusted diluted EPS is a company’s profit per share after adding back or removing one-time items (like restructuring costs or gains) and dividing by the number of shares including potential shares from options and convertible securities. Investors use it as a cleaner view of ongoing earnings—like looking at a car’s regular fuel efficiency rather than a trip boosted by downhill coasting—to judge underlying performance and compare companies without temporary distortions.

Say on Pay financial

"To conduct an advisory vote to approve compensation of named executive officers."

Say on pay is a shareholder vote—typically nonbinding—on a company’s executive compensation package, allowing investors to approve or reject how top managers are paid. Think of it as a public performance review: widespread disapproval can signal poor governance, prompt changes to pay practices, attract activist investors, and influence investor confidence and share value. It matters because it gives owners a direct way to influence compensation that affects company incentives and long-term performance.

broker non-vote regulatory

"the withholding of which is referred to as a “broker non-vote.”"

clawback policy regulatory

"Clawback Policy Code of Business Conduct and Ethics Corporate Governance Principles"

A clawback policy is a company rule that lets the firm take back pay, bonuses or stock awards from current or former executives if results are later found to be incorrect, misconduct occurred, or targets were missed. It matters to investors because it helps protect the value of their holdings by discouraging risky or fraudulent behavior and ensuring executive rewards reflect real, verified performance—think of it as a return policy for executive pay.

Lead Independent Director financial

"David P. Falck (Lead Independent Director)"

A lead independent director is a board member who is not part of company management and is chosen to coordinate and represent the other independent directors, often running sessions without the CEO, helping set meeting agendas, and serving as a liaison between shareholders and the board. For investors, this role signals stronger, more balanced oversight—like a neutral referee who helps ensure decisions are fair, transparent and focused on protecting shareholder interests.

Nominating/Corporate Governance Committee regulatory

"Nominating/Corporate Governance Committee Charter"

A nominating/corporate governance committee is a small group of a company’s board members tasked with choosing and evaluating directors and setting the rules that guide how the board operates. Think of it as the board’s hiring and rule-making team: it shapes leadership, board makeup, independence and ethical standards, which in turn influence how well the company is overseen and how investor interests are protected.

Executive Compensation

At the 2025 Annual Meeting of Stockholders, the Company’s stockholders cast a non-binding advisory vote to approve the compensation of the Company’s named executive officers as disclosed in the proxy statement for that meeting. The Company’s stockholders overwhelmingly approved the proposal with more than 91% of the shares voted being cast in favor of the proposal. These programs and policies remain unchanged, as described in detail beginning on page 31. The Company’s core management compensation program includes base salary, an annual incentive plan payment opportunity, an annual stock option award (with 20% vesting each year over a five-year period), insurance benefits and retirement benefits.

The compensation program for the named executive officers emphasizes at-risk, performance-based elements. Fixed compensation elements, including base salary, retirement benefits and other compensation are designed to be market competitive for purposes of retention, and to a lesser extent, recruitment. However, it is intended that a larger part of the named executive officers’ compensation be designed to reward performance that generates long-term shareholder value.

For the Company’s Chief Executive Officer, fixed compensation elements including salary and “all other compensation” (which includes retirement benefits) comprised approximately 9% of his total 2025 compensation. His at-risk compensation linked to increasing shareholder value comprised approximately 91% of his total 2025 compensation. These at-risk elements include stock options granted with an exercise price equal to the closing price of the Common Stock on the date of grant which only generate value if the Company’s share price increases after the grant date. The other at-risk compensation is annual incentive plan compensation which historically has not paid out if year-over-year Adjusted Diluted EPS declines and rewards the Chief Executive Officer for growth in Company revenues and Adjusted Diluted EPS. For the Company’s other named executive officers as a group, fixed compensation elements comprised approximately 15% of total 2025 compensation while at-risk compensation comprised approximately 85% of total 2025 compensation. As with the Chief Executive Officer, the fixed compensation elements for the other named executive officers include salary and “all other compensation,” while the at-risk items include stock options and annual incentive plan compensation linked to goals that encourage growth in revenues and either Adjusted Diluted EPS or operating income, depending on the role of the named executive officer.

The Board believes this compensation program is a valuable and appropriate tool which contributes to the Company’s continuing success.

Only stockholders of record at the Record Date are entitled to notice of and to vote at the Annual Meeting and any postponements or adjournments thereof. At the Record Date, there were 1,229,430,709 shares of Common Stock outstanding.

The Notice also provides instructions on how to vote over the Internet. If you received a Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request these materials. Other stockholders, in accordance with their prior requests, have been mailed paper copies of our proxy materials and a proxy card and/or a voter instruction form from their bank, broker or other nominee.

Internet distribution of proxy materials is designed to expedite receipt by stockholders, lower the cost of the Annual Meeting, and reduce the environmental impact of the Annual Meeting. However, if you received a Notice by mail and would like to receive a printed copy of our proxy materials, please follow the instructions for requesting such materials contained in the Notice.

PROXIES AND VOTING

The proxy accompanying this proxy statement is solicited on behalf of the Board for use at the Annual Meeting and any postponements or adjournments thereof. Each holder of Common Stock is entitled to one vote for each share of Common Stock held at the Record Date. The holders of record, present in person or by proxy, of a majority of the issued and outstanding shares of Common Stock shall constitute a quorum. If a stockholder votes in person, by telephone, over the Internet or by returning a properly executed proxy card, the stockholder will be considered a part of that quorum. Abstentions and broker non-votes (i.e., when a broker does not have authority to vote on a specific proposal) are counted as present for quorum purposes.

Shares will be voted in accordance with stockholder instructions. If a stockholder received printed versions of the proxy materials by mail, these printed proxy materials also include the proxy card for the Annual Meeting, and the stockholder may complete, date, sign and return the proxy card in accordance with the voting instructions on the proxy card, whether or not the stockholder plans to attend the Annual Meeting. If a stockholder received a Notice, the Notice will contain instructions regarding how to vote by Internet or by telephone and how to request printed versions of the proxy materials by mail.

In order for a vote to be counted, the stockholder must (i) return a completed and signed proxy card so that it is received by mail by the Company’s transfer agent before the date of the Annual Meeting, (ii) vote by Internet or by telephone prior to the date of the Annual Meeting or (iii) vote at the Annual Meeting if the stockholder is attending.

In the event that a stockholder returns a signed proxy card that omits voting instructions for some or all matters to be voted on or indicates when voting by telephone or over the Internet that the stockholder wishes to vote as recommended by the Board, the proxy holders will vote in accordance with the recommendations of the Board on each of the matters presented in this proxy statement for which specific voting instructions were not provided. In addition, the proxy holders will have, and intend to exercise, discretion to vote shares in

accordance with their best judgment on any matters not identified in this proxy statement on which a vote is taken at the Annual Meeting. At present, the Company is not aware of any such matter.

Stockholders that hold their shares in “street name” through an account with a broker, bank or other nominee must follow the directions provided by such broker, bank or other nominee regarding how to provide voting instructions. For stockholders that hold their shares in “street name” through an account with a broker, bank or other nominee, and do not give voting instructions on a matter, under the rules of the New York Stock Exchange, the broker, bank or other nominee, is permitted to vote in its discretion only on Proposal 2 (ratification of selection of the independent public accountants) and is required to withhold its vote on each of the other proposals, the withholding of which is referred to as a “broker non-vote.”

The following table illustrates votes required, and the impact of abstentions and broker non-votes.

For shares that are held through an account with a broker, bank or other nominee, the stockholder must follow the directions provided by its bank, broker or other nominee for revoking or modifying voting instructions. For shares that are registered in the stockholder’s own name, the proxy may be revoked (a) at any time before the Annual Meeting by (i) providing written notification to the Company Secretary prior to its exercise and providing relevant name and account information, (ii) if a stockholder has received printed proxy materials, submitting a new proxy card by mail with a later date (which will override the earlier proxy) or (iii) re-voting by telephone or over the Internet (only the latest telephone or Internet vote will be counted); or (b) by attending the Annual Meeting and voting in person at the Annual Meeting, which will automatically cancel any proxy previously given (but attendance alone will not revoke any proxy that you have previously given).

The inspectors of election appointed for the Annual Meeting with the assistance of the Company’s transfer agent, Computershare Trust Company, N.A., will determine if a quorum is present and tabulate the votes.

TABLE OF CONTENTS

PROPOSAL 1. ELECTION OF EIGHT DIRECTORS

The Restated Certificate of Incorporation, as amended from time to time, and the By-Laws of the Company (the “By-Laws”), taken together, provide for a Board consisting of not less than three or more than 15 directors. Our directors are elected annually.

Currently, the number of directors of the Company is nine. Martin H. Loeffler is not standing for re-election at the Annual Meeting. Accordingly, action will be taken at the Annual Meeting for the election of eight directors: Nancy A. Altobello, David P. Falck, Sanjiv Lamba, Rita S. Lane, Robert A. Livingston, R. Adam Norwitt, Prahlad Singh and Anne Clarke Wolff for a term of one year that will expire at the 2027 Annual Meeting. The Company thanks Mr. Loeffler for his many years of dedicated service.

In accordance with our By-Laws, directors are elected by a majority of the votes cast in uncontested elections. That means the nominees will be elected if the number of votes cast “for” a director’s election exceeds the number of votes cast “against” such nominee. Our form of proxy permits you to abstain from voting “for” or “against” a particular nominee. Abstentions will count as being present for purposes of determining a quorum and will not count as a vote cast and so will have no effect on the election of directors. Broker non-votes will not count as votes cast and will have no effect on the elections of directors.

In the event that any nominee fails to receive the required vote for re-election, the Nominating/Corporate Governance Committee of the Board must then consider whether to accept the director’s resignation, previously tendered in accordance with the Company’s Corporate Governance Principles, and make a recommendation to the Board. The Board will then consider the resignation, and within 90 days after the date of certification of the election results or any extension of such period, publicly disclose its decision and the reasons for its decision.

It is intended that the proxies delivered pursuant to this solicitation will be voted in favor of the election of each director nominee, except in cases of proxies bearing contrary instructions. Each nominee has indicated that he or she will serve if elected, and the Board has no reason to believe that any of the nominees named above will become unavailable for election as a director, but in the event that any of these nominees should become unavailable for election for any presently unforeseen reason, the persons named in the proxy will have the right to use their discretion to vote for a substitute.

Information regarding each director nominee that led the Board to conclude that the director should serve on the Board is set forth in the biographical descriptions on the following pages and in the table on page 17 under the heading Board of Directors Summary Information. The Company’s goal is to assemble a Board that works together and with management to deliver long-term shareholder value. The Company believes that the nominees and directors set forth below, each of whom is currently a director of the Company, possess the skills and experience necessary to guide the Company in the best interests of its stockholders. The Company’s current Board consists of individuals with proven records of success in their chosen professions and with the Company. They all have high integrity and keen intellect. They are collegial yet independent in their thinking, and have demonstrated the willingness to make the time commitment necessary to be informed about the Company and its relevant industry, including its customers, suppliers, competitors, stockholders and management.

The following information details the professional experience and other directorships of public companies during at least the past five years for each of the proposed director nominees. Beneficial ownership of equity securities of the current directors and the proposed director nominees is shown under the caption Security Ownership of Directors and Executive Officers on page 5.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR EACH OF THE
NOMINEES FOR ELECTION TO THE BOARD OF DIRECTORS.

TABLE OF CONTENTS

THE BOARD OF DIRECTORS AND THE COMMITTEES OF THE BOARD

Governance Principles

Amphenol’s Corporate Governance Principles meet or exceed the Listing Standards of the New York Stock Exchange (the “NYSE Listing Standards”), including guidelines for determining director independence and reporting concerns to non-employee directors and the Audit Committee. The Company’s Corporate Governance Principles, the Code of Business Conduct and Ethics and the charters of each of the Board’s committees are reviewed at least annually and revised as warranted. Amphenol’s Code of Business Conduct and Ethics applies to all employees, directors and officers of the Company and its subsidiaries.

The Company posts the following documents on its website at www.amphenol.com under the heading “Investors”, then “Governance,” and then “Governance Documents”:

The Company posts the following charters for its Board committees on its website at www.amphenol.com under the heading “Investors,” then “Governance,” then “Board of Directors” and then “Committee Charters”:

Audit Committee Charter
Compensation Committee Charter
Executive Committee Charter
Finance Committee Charter
Nominating/Corporate Governance Committee Charter

Director Independence

The Board has adopted the definition of “independent director” set forth in the NYSE Listing Standards to assist it in making determinations of independence. In addition to applying these guidelines, the Board will consider all relevant facts and circumstances in making an independence determination.

The Board has determined that all of the directors are independent of the Company and its management with the exception of Mr. Norwitt who is not considered an independent director because of his current employment with the Company. In addition, Mr. Edward G. Jepsen was independent during his service on our Board in 2025.

Leadership Structure

Our Board believes it is important to retain flexibility to determine its optimal leadership structure in light of a variety of factors at any given time, including the particular composition of the Board as well as the specific needs and opportunities of the Company. With any leadership structure, it is critically important to have a strong relationship between the independent directors and management. Following Mr. Loeffler’s announcement that he would not stand for re-election to the Board, the Board determined that implementing a combined Chairman/Chief Executive Officer and Lead Independent Director structure is the appropriate leadership structure at this time to balance between the most effective operation of the Board and independent oversight of management. This leadership transition is the result of robust succession planning and thoughtful deliberation by the full Board.

TABLE OF CONTENTS

The Board’s decision to combine the roles of Chairman and Chief Executive Officer under Mr. Norwitt reflects the Board’s strong belief that he has demonstrated the leadership and strategic vision necessary to lead the Board and the Company. The Board believes that Mr. Norwitt’s extensive tenure and success with the Company, together with his deep familiarity with the culture of Amphenol and knowledge of the day-to-day business, best positions him to help the Board focus on the issues of greatest importance to the Company and assist the Board in identifying the short-term and long-term risks and challenges facing the Company.

The Board also recognizes that with a combined Chairman and Chief Executive Officer structure, it is imperative to have a strong Lead Independent Director with a clearly defined set of responsibilities to provide independent leadership and oversight and to help ensure sound Board decision-making. David P. Falck, who has served as a director since 2013 and as Presiding Director since 2016, has been appointed to serve as Lead Independent Director. Mr. Falck’s extensive experience advising public companies and broad knowledge of our business make him well situated to guide the Board in its oversight of the Company and to foster open dialogue among the independent directors and management. In his role as Lead Independent Director, Mr. Falck will be responsible for developing agendas for executive sessions of independent directors and calling and presiding over the same. Mr. Falck will also serve as a liaison between the Chairman and the independent directors, review meeting agendas and meeting schedules, review stockholder communications directed to the Board and take appropriate action and consult with the Chairman on such other matters as are pertinent to the Board and the Company.

TABLE OF CONTENTS

Board of Directors Summary Information

The following table sets forth basic information about the experience, skills and backgrounds that our Board considered important in its decision to re-nominate those individuals to our Board. Except for those directors identified as an “audit committee financial expert” (as defined by the applicable rules of the SEC and the NYSE Listing Standards) elsewhere in this proxy statement, the fact that a nominee has an “●” marked next to his or her name for a particular skill does not necessarily mean that the nominee is an “expert” in that area, but rather, the mark signifies that the nominee brings meaningful skills and experience to the Board in that particular subject. Each director nominee is individually qualified to make unique, substantial and important contributions. Collectively, our directors’ diverse viewpoints and independent-mindedness enhance the quality and effectiveness of Board deliberations and decision making.

Director Selection Process

The Nominating/Corporate Governance Committee will consider candidates for Board membership suggested by its members and other Board members, as well as by management and stockholders. A stockholder may recommend any person for consideration as a nominee for director by writing to the Nominating/Corporate Governance Committee, c/o Secretary, Amphenol Corporation, 358 Hall Avenue, Wallingford, CT 06492. Recommendations must be received by December 31, 2026 to be considered for inclusion in the proxy statement for the 2027 Annual Meeting of Stockholders and must comply with the requirements in the Company’s By-Laws. Recommendations must include the name and address of the

TABLE OF CONTENTS

stockholder making the recommendation, a representation that the stockholder is a holder of record of Common Stock, biographical information about the individual recommended and any other information the stockholder believes would be helpful to the Nominating/Corporate Governance Committee in its evaluation of the individual being recommended by the stockholder as a nominee for director.

Potential candidates for the Board will be evaluated by the Nominating/Corporate Governance Committee on the basis of:

•

character, judgment, personal and professional ethics, integrity and values;

•

business, financial and/or other applicable experience;

•

familiarity with national and international issues affecting the Company’s business;

•

depth of experience, skills and knowledge complementary to the Board and the Company’s business; and

•

ability and willingness to devote sufficient time to effectively carry out the duties and responsibilities of a director of the Company.

The Board believes it functions most effectively when comprised of a diverse set of members, including a healthy mix of short-, mid- and long-serving members. To that end, the Board is committed to a policy of regular refreshment and has regularly engaged a reputable international search firm to identify appropriate candidates. Since 2018, we have added six new independent members to our Board, Anne Clarke Wolff, Robert Livingston, Rita Lane, Nancy Altobello, Prahlad Singh and Sanjiv Lamba.

Our Board also believes that diversity includes diversity with respect to background, culture, skills, age, experience and expertise. The Nominating/Corporate Governance Committee may also consider such other relevant factors as it deems appropriate. It will make a recommendation to the full Board as to any persons it believes should be nominated by the Board, and the Board will determine the nominees after considering the recommendation and report of the Nominating/Corporate Governance Committee. The process for considering candidates recommended by a stockholder for Board membership will be no different than the process for candidates recommended by members of the Nominating/Corporate Governance Committee, other members of the Board or management. In connection with the identification and appointment of Ms. Wolff, Mr. Livingston, Mr. Lamba, Ms. Lane and Mr. Singh, the Board engaged a reputable international search firm. In the case of Ms. Altobello, the Board did not engage a search firm, but instead became aware of her in connection with the Company’s acquisition of MTS Systems Corporation, where she was already a board member.

Committees

The Board has five standing committees: the Audit Committee, the Compensation Committee, the Executive Committee, the Finance Committee and the Nominating/Corporate Governance Committee. The Board has determined that all the members of the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee are independent and satisfy the relevant SEC and New York Stock Exchange independence requirements for the members of such committees. The Board also has determined that all members of the Executive Committee and the Finance Committee are independent.

Meetings of the Board and Committees

During 2025, there were nine meetings of the Board. During 2025, the Audit Committee had six meetings, the Compensation Committee had four meetings, the Nominating/Corporate Governance Committee had two meetings and the Finance Committee had two meetings. Except for two directors missing one special Board meeting, all directors participated in all meetings of the Board and the committees on which he or she served in 2025. Directors also attended meetings as invited guests of all committees on which they did not serve. This included quarterly telephonic meetings of the Audit Committee during which quarterly results were discussed and quarterly press releases reporting operating results were reviewed and approved.

The independent directors of the Company meet in executive session as necessary, but at least quarterly as part of the Board’s regular quarterly meetings. Such private meetings are currently presided over by the Lead Independent Director, the chair of the committee or the director who requests the opportunity to meet in executive session.

The full Board conducts a self-evaluation at least annually to determine whether it and its committees are functioning effectively. The full Board meets at least annually with the Audit Committee, the Compensation Committee, the Executive Committee, the Finance Committee and the Nominating/Corporate Governance Committee to review and discuss each committee’s self-evaluation, including its performance as measured against its charter and the continuing effectiveness of its charter. In addition, the Board discusses with the Nominating/Corporate Governance Committee the corporate governance principles that it is responsible for developing and recommending to the Board.

Risk Oversight

The Board is actively involved in overseeing risk management for the Company. This oversight is conducted both directly and through the committees of the Board. At each regularly scheduled quarterly meeting of the Board, the Board reviews various risks facing the Company at such time.

TABLE OF CONTENTS

The Audit Committee reviews the Company’s portfolio of risk with management and the Company’s independent public accountants, discusses with management significant financial risks, the Company’s policies with respect to risk assessment and risk management and the actions management has taken to limit, monitor and control financial and other risk exposures. The Audit Committee also reviews the Company’s internal system of audit and financial controls and the process for maintaining financial reporting controls with management and the Company’s independent public accountants. The Audit Committee also assists the Board in fulfilling its responsibility for oversight of cybersecurity and climate-change related matters, which are reviewed as appropriate with the Board.

The Compensation Committee oversees risk management as it relates to compensation plans, policies and practices in connection with structuring the Company’s executive compensation programs and incentive compensation programs for other employees. The Compensation Committee reviews with management whether the compensation programs, including the incentive plans and the stock option plans described in the section entitled Elements of Compensation Program beginning on page 32, are reasonably likely to create incentives for employees that may cause such employees to take excessive or inappropriate risks which could have a material adverse effect on the Company. The Compensation Committee and management have concluded that the Company’s compensation programs are not reasonably likely to create incentives for employees that may cause such employees to take excessive or inappropriate risks which could have a material adverse effect on the Company.

The Nominating/Corporate Governance Committee oversees risk management as it relates to governance matters.

The Finance Committee oversees risk management as it relates to certain financial affairs of the Company.

Corporate policies encourage employees to report possible violations of Company policy, or any other illegal or unethical conduct by employees, officers or directors of Amphenol, to the employee’s manager, the Amphenol Legal Department, the Audit Committee or the Company ethics hotline. The Audit Committee reviews the reporting, where appropriate. During each of the Company’s monthly management operation reviews, the Chief Executive Officer and Chief Financial Officer provide feedback on risk management practices to the operating management teams. The operating management teams are required to consider risks and risk mitigation strategies as part of their annual budget processes and strategic planning processes and to include specific mitigation strategies.

Cybersecurity Governance

The Board maintains oversight responsibility relating to our cybersecurity risk management program (the “Program”), with assistance from the Audit Committee. At least annually, the Company’s management team (including the leaders of its Information Technology and Internal Audit teams) provides an update regarding the Program to the Board. This update provides an overall assessment of the effectiveness of the Program and a review of areas of focus for the upcoming year. The Board also receives periodic reports from the Vice President, Internal Audit, on the audit focus areas and control testing related to the Company’s information security systems and security controls, and the management team updates the Board, where it deems appropriate, regarding any significant cybersecurity incidents.

Human Capital Management and Our Culture

The Board is actively involved in overseeing the Company’s culture as well as employee-related strategies and practices. 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. 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 both executive management and the Board.

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

TABLE OF CONTENTS

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. Our core management team is comprised of these general managers and their controllers, as well as our group general managers and executive management team.

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.

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 tailor-made to support the specific needs of the local communities in which our employees live and work.

Oversight of Sustainability Matters

Our Board oversees the Company’s sustainability strategies and initiatives. The Audit Committee assists the Board in fulfilling its oversight responsibility for the “environmental” component of sustainability, which includes periodic review of the Company’s climate-change related strategies, policies, disclosures, goals, performance and measurement, including with respect to greenhouse gas emissions, energy and water usage and any other relevant subjects as determined by the Company and monitoring the effectiveness of Company systems necessary to ensure compliance with applicable legislation, regulatory requirements, industry standards and Company policies, programs and practices relevant to climate-change related matters. The Compensation Committee is responsible for assisting the Board in fulfilling its oversight responsibility for the “social” component of sustainability, which includes reviewing the Company’s human capital management programs and performance. The Nominating/Corporate Governance Committee’s responsibilities include assisting the Board in fulfilling its oversight responsibility for the “governance” component of sustainability, which includes (a) developing and recommending to the Board a set of corporate governance principles applicable to the Company, (b) reviewing and recommending to the Board responses to shareholder proposals for inclusion in the Company’s proxy statement and (c) reviewing and evaluating governance trends, rules and best practices to determine any impact on the Company and potential changes for consideration. Amphenol’s sustainability initiatives are governed by a structure of leadership, oversight and goals that encompass our entire Company. These initiatives are governed by a number of policies which outline our principles including in particular our Code of Business Conduct and Ethics, Environmental Policy, Global Human Rights Policy and our Health and Safety Policy. All of these documents are available on our website at https://www.amphenol.com/sustainability, except for our Code of Business Conduct and Ethics, which can be found at www.amphenol.com under the heading “Investors,” then “Governance,” and then “Governance Documents.” For more information about our Board’s oversight of sustainability matters, please visit the sustainability section of our website at https://www.amphenol.com/ sustainability as well as our most recent Sustainability Report available there.

This column represents the amount of cash compensation earned for service on our Board and its committees.

The grant date fair value of the 2,360 shares of restricted stock granted to each director (other than Mr. Jepsen) on May 16, 2025 was $205,037 computed in accordance with FASB ASC Topic 718. Unless the date of the Annual Meeting is postponed, which is not currently expected, the restricted stock awards granted to each of the directors indicated in the table above will become fully vested on May 20, 2026.

(3)

The Company does not have a pension plan program applicable to its non-employee directors. Directors who are current or former employees participate in the Company’s Pension Plan (described beginning on page 48) as employees. Messrs. Jepsen and Loeffler participated in the Pension Plan during their prior employment with the Company. Upon retirement, their pension benefits were fixed, and they are no longer accruing any additional benefits under the Pension Plan.

(4)

The Company does not have any other compensation programs for its non-employee directors, nor did it provide any other benefits which could be deemed to be compensation for their service.

(5)

Mr. Jepsen did not stand for re-election at the May 15, 2025 Annual Meeting of Stockholders. His 2025 compensation reflects amounts paid to him through such date.

The Compensation Committee reviews compensation for the non-employee directors at the beginning of each calendar year. In connection with its review, the Compensation Committee retains Meridian Compensation Partners, LLC (“Meridian”), an independent compensation consultant, to provide market data for director compensation at companies similar in size to Amphenol. For more information on Meridian, see the section entitled Role of Compensation Consultant in Compensation Decisions in the Compensation Discussion and Analysis section.

In January 2025, in connection with its regular and ongoing review of Board compensation, the Board adopted changes to the fee amounts earned by the directors as outlined in the table below effective January 1,

TABLE OF CONTENTS

2025. These fees were last adjusted in 2022. In connection with such changes, Meridian confirmed that the increased fees were aligned with market practice.

Annual Fees Earned by Non-Employee Directors
	2022 to 2024			2025 Adjusted Amounts
Annual Retainer Fee		$	100,000		$	115,000
Fee for Chairman of the Board		$	180,000		$	210,000
Fee for Lead Independent Director		$	35,000		$	45,000
Fee for Audit Committee Chair		$	25,000		$	30,000
Fee for Other Committee Chairs		$	15,000		$	20,000
Value of Equity Grant		$	180,000*		$	205,000*

The 2024 Restricted Stock Plan for Directors of Amphenol Corporation (the “Directors Restricted Stock Plan”), which was approved by stockholders in May 2024, provides for annual grants of restricted stock to the non-employee directors on the first business day after each annual meeting of stockholders and interim pro-rated grants for non-employee directors not initially elected at a regular meeting of the Company’s stockholders. On the grant date, each non-employee director will be awarded shares of Common Stock subject to the restrictions and conditions in the Directors Restricted Stock Plan. In 2025, the number of shares granted was determined by dividing $205,000 by the closing price for the Common Stock on the grant date and rounding up to the next whole share amount. The closing price of the Common Stock on May 16, 2025 was $86.88

In February 2026, in connection with its regular and ongoing review of Board compensation and after consultation with Meridian, the Board increased the fee payable to the Lead Independent Director from $45,000 to $50,000. This change was made in anticipation of Mr. Loeffler’s retirement from the Board and the concurrent appointment of Mr. Norwitt, a non-independent director, as Chairman of the Board effective on the date of the Annual Meeting. Upon his appointment, Mr. Norwitt will not be paid the separate Chairman fee for his role as Chairman of the Board. No other changes were made with respect to the fees payable to the Board in 2026.

Going forward, the Compensation Committee will continue to monitor and make recommendations to the Company and to the Board regarding the annual retainer fee, committee chair fees, Chairman of the Board fee, if any, Lead Independent Director fee and equity compensation elements of the directors’ compensation program to ensure that total director compensation is fair and reasonable and competitive for the purpose of attracting and retaining qualified directors.

Communications with the Board of Directors

Stockholders and other interested parties may communicate directly with members of the Board of Directors c/o Secretary, Amphenol Corporation, 358 Hall Avenue, Wallingford, CT 06492. All communications will be promptly forwarded to the appropriate directors for their review, except that the Board has instructed the Secretary not to forward solicitations, bulk mail or communications that address improper or irrelevant topics or requests for general information.

Board Member Attendance at Annual Meeting of Stockholders

In each of the last ten years, more than 85% of outstanding shares of Common Stock have been voted by proxy and no more than five non-employee stockholders (representing only a nominal number of shares) have personally attended any of the Company’s annual meetings of stockholders. Accordingly, the Company does not require members of the Board to attend the annual meetings of stockholders. The only then-current Board member who attended the 2025 Annual Meeting of Stockholders was Mr. Norwitt.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee has undertaken a review of its charter, practices and procedures in order to assure continuing compliance with the provisions of the Sarbanes-Oxley Act of 2002 and related regulatory requirements promulgated by the Securities and Exchange Commission and the New York Stock Exchange. Following that review, the Audit Committee confirmed its charter, practices and procedures. The Audit Committee Charter is available on the Company’s website at www.amphenol.com by clicking on the heading “Investors,” then “Governance,” then “Board of Directors,” then “Audit Committee Charter” or by entering the URL https://www.amphenol.com/docs/audit-committee-charter into your web browser’s address bar. In addition, a printed copy of the most current Audit Committee Charter will also be provided to any stockholder free of charge upon written request to Amphenol Corporation, Secretary, 358 Hall Avenue, Wallingford, Connecticut 06492.

The Audit Committee reports as follows:

The Audit Committee has reviewed and discussed the Company’s audited financial statements for the year ended December 31, 2025 with Company management, which has primary responsibility for establishing and maintaining adequate internal financial controls, preparing the Company’s quarterly and annual financial statements and for the Company’s public reporting process, and with Deloitte & Touche LLP, the Company’s independent public accountants for 2025, which is responsible for expressing an opinion on the conformity of the Company’s audited financial statements with generally accepted accounting principles and its own assessment of the Company’s internal control over financial reporting.

The Audit Committee has discussed with Deloitte & Touche LLP those matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC.

The Audit Committee has received the letter and written disclosures from Deloitte & Touche LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent public accountant’s communications with the Audit Committee concerning independence and has discussed with Deloitte & Touche LLP that firm’s independence. The Audit Committee has also determined that Deloitte & Touche LLP’s provision of audit and non-audit services to the Company is compatible with that firm’s independence.

Based on the review and discussions referred to above, the Audit Committee has recommended to the Board and the Company that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the Securities and Exchange Commission. The Audit Committee has also selected Deloitte & Touche LLP as independent public accountants of the Company for fiscal year 2026.

PRE-APPROVAL OF AUDITOR SERVICES

The Audit Committee has adopted and implemented approval policies and procedures related to the provision of permissible audit, audit-related, tax and other non-audit services by the Company’s independent public accountants. Under these procedures, the Audit Committee has pre-approved the use of the Company’s independent public accountants for specific types of services. These specific types of services include, but are not limited to, audits, services provided in connection with audits, merger and acquisition due diligence, tax services, internal control reviews and reviews of employee benefit plans. The Audit Committee has elected to delegate pre-approval authority to the Chair of the Audit Committee. For services by the Company’s independent public accountants which are not specifically listed, the Chair of the Audit Committee has pre-approval authority for engagements where the estimated cost of such services is not expected to exceed $25,000. All engagements performed by the Company’s independent public accountants are to be reported to the Audit Committee on no less frequently than a quarterly basis. Any permitted services by the independent public accountants where the estimated cost of such services is expected to exceed $25,000 for any given project must be pre-approved by the Audit Committee to ensure compatibility with maintaining the accountants’ independence. In 2025, all fees for permitted services were pre-approved in accordance with these policies.

HIRING RESTRICTIONS ON FORMER EMPLOYEES OF AUDITOR

The Audit Committee has also reviewed and confirmed Company policies and procedures imposing restrictions on the hiring of certain individuals employed by or formerly employed by the Company’s independent public accountants, including any employee or former employee of the Company’s independent public accountants who currently has or who has previously had any responsibility for the performance of any audit work for the Company or any involvement with the certification of the Company’s financial statements.

TABLE OF CONTENTS

PROPOSAL 2. RATIFICATION OF THE SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS

The Audit Committee of the Board of Directors has considered the performance and qualifications of Deloitte & Touche LLP and has selected Deloitte & Touche LLP to act as independent public accountants to examine the financial statements of the Company for the current fiscal year. Deloitte & Touche LLP has acted as independent public accountants for the Company since 1997, and the Audit Committee and management have considered and believe it desirable and in the best interests of the Company to continue the engagement of that firm. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. Such representatives are expected to have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

If the selection of Deloitte & Touche LLP is not ratified by an affirmative vote of a majority of the votes cast at the Annual Meeting, the Audit Committee will review its future selection of independent public accountants in light of that result.

The Board is asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the selection by the Audit Committee of the Board of Directors of the firm of Deloitte & Touche LLP as independent public accountants for the Company for the year 2026 is hereby RATIFIED.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE ADVISORY RESOLUTION FOR RATIFICATION OF SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS.

COMPENSATION DISCUSSION & ANALYSIS

Overview of Compensation. The Compensation Committee of the Board (referred to in this Compensation Discussion & Analysis as the “Committee”) has responsibility for establishing, implementing and continually monitoring adherence with the Company’s compensation philosophy and guidelines. A primary goal of the compensation philosophy and these guidelines is to align the interests of management with the interests of stockholders to drive long-term shareholder value through performance. The Committee strives to ensure that the total compensation paid to executive officers and key management employees is appropriate and reasonable, while, at the same time, capable of attracting, motivating and retaining the executive officers and key management employees of the Company. The Committee endeavors to keep the structure of the Company’s compensation programs simple, transparent, consistent and broad-based. The Company’s core management compensation program includes base salary, an annual incentive plan payment opportunity, annual stock option awards, insurance benefits and retirement benefits. This core compensation structure has not changed in more than 25 years.

Throughout this proxy statement, the Company’s Chief Executive Officer and the Chief Financial Officer together with the three other individuals included in the Summary Compensation Table on page 43, are referred to as the “named executive officers.” References to “executive officers and key management employees” in this proxy statement relate to the approximately 1,300 management personnel of the Company, including the named executive officers, who participated in the Company’s core management compensation programs in 2025.

Say on Pay. At the 2025 Annual Meeting, the Company’s stockholders cast a non-binding advisory vote to approve the compensation of the Company’s named executive officers as disclosed in the proxy statement for the 2025 Annual Meeting of Stockholders. The proposal received overwhelming support with more than 91% of the shares voted being cast in favor of the proposal. The Board appreciates this show of support, which reaffirms to the Board that the Company’s current management compensation policies and programs support our stockholders’ objectives. The Company believes the philosophy and objectives of its management compensation program, as well as the implementation of the elements of the compensation program, are appropriately geared towards aligning the interests of management with the interests of stockholders to drive long-term shareholder value. No changes were made to the structure of the Company’s core management compensation programs in 2025 or 2026.

The Compensation Committee. The Committee is currently composed of four independent directors. The activities and actions of the Committee are subject to the review of the full Board. All actions of the Committee are reported to the Board no later than the next subsequent meeting of the full Board following any Committee action.

The Committee has responsibility, from time to time, but at least annually, to:

•

Review and approve the overall compensation philosophy and guidelines for all executive officers and key management employees of the Company and its subsidiaries.

•

Review and approve changes as necessary and appropriate to the Company’s annual Management Incentive Plan and the Company’s Stock Option Plan as described beginning on pages 33 and 35, respectively.

•

Review and approve the goals relevant to compensation for, and evaluate the performance of, the Company’s Chief Executive Officer; determine and approve, as deemed necessary and appropriate, any changes in his compensation; and approve any incentive plan payments and/or any option awards to the Company’s Chief Executive Officer.

•

Review and approve recommendations from the Company’s Chief Executive Officer related to the incentive plan payments and stock option awards and other related matters for all other executive officers and key management employees.

•

Review and approve recommendations from the Company’s Chief Executive Officer related to specific adjustments to individual base salary and incentive plan targets for all executives reporting directly to the Chief Executive Officer, the Division Controllers and Group General Managers and any other employees comprising the 20 most highly compensated employees.

Role of Compensation Consultant in Compensation Decisions. The Committee has retained Meridian, an independent compensation consultant, to advise it from time to time on executive and board compensation matters. Meridian reports directly to the Committee and the Committee has sole authority to negotiate the terms of service, including all fees paid to Meridian. In 2025, in conjunction with the Committee’s annual review of executive compensation, Meridian was asked to provide market data for executive compensation at companies similar in size to Amphenol. Meridian does not make any decisions relating to the creation or implementation of the Company’s compensation policies or programs. The Committee and Meridian both evaluated Meridian’s independence in 2025 and concluded that Meridian is independent of the Company.

Role of Executive Officers in Compensation Decisions. In establishing, reviewing and assessing the appropriateness of compensation levels and adjustments in compensation levels for the executive officers (other than the Chief Executive Officer) and key management employees, the Committee considers the recommendations of certain executive officers of the Company, including in particular Mr. Norwitt. Mr. Norwitt and certain executive officers of the Company review the performance and compensation of the executive officers and key management employees at least annually and any prospective senior management employees as necessary. As part of this process, Mr. Norwitt and such executive officers consider market data provided by Meridian as well as general compensation surveys comprised of widely available information which is generally accessible for purchase or provided without charge to the Company in exchange for participation in the survey. The Company’s human resources department, including the Executive Vice President, Human Resources, also provides data, information and feedback based on its general knowledge of compensation inside and outside of the Company. The accounting department and legal department, including the executive officers in those departments, also compile and analyze data and share this with Mr. Norwitt. The recommendations of these executive officers, including Mr. Norwitt, regarding any salary adjustments, annual incentive plan payments and annual option awards based on individual and operating unit performance, are presented to the Committee. The Committee exercises its discretion in modifying and approving any such recommendations. Mr. Norwitt consults with the Committee on essentially all compensation matters but does not participate in the evaluation or determination of his own compensation.

Mr. Norwitt does not vote on any compensation matters considered by the Committee. However, he is available to the Committee as an additional resource to respond to questions and discuss individual and operating unit performance, as well as related compensation matters. The Committee also meets informally from time to time and in executive session following each meeting to discuss compensation matters without Company employees present.

Philosophy and Objectives of Compensation Program. The Committee continues to strive to develop, refine and implement a complete, consistent and straightforward compensation program that helps to attract, motivate and retain the executive officers and key management employees, and that remains competitive with comparable companies. The program is designed to promote decision making geared to increasing long-term shareholder value while avoiding excessive risk taking. The Committee believes that to further these objectives, executive compensation packages should include both cash and long-term equity-based compensation as well as reasonable benefits.

Elements of Compensation Program. The Committee endeavors to provide an appropriate mix of different elements of compensation, including finding a balance among (i) fixed versus at-risk compensation, (ii) current versus long-term compensation, (iii) cash versus equity-based compensation and (iv) basic benefits. Cash payments primarily reward current year performance and equity-based awards encourage key management employees, including the named executive officers, to continue to deliver results over a longer period of time and serve as a retention tool. The Committee generally strives to provide equity-based compensation at a level sufficient to drive an appropriate amount of focus on the long-term performance of the Company. The compensation program for executive officers and key management employees, including the named executive officers, generally includes the following elements:

•

Base Salary

•

Annual Cash Incentive Plans

•

Stock Option Plans

TABLE OF CONTENTS

•

Insurance Benefits

•

Retirement Benefits

Base Salary. The Company establishes base salary to provide fixed income at approximately the median level for executives of comparable companies with similar responsibilities. Several elements are considered in setting base salary, including the size, scope and complexity of the executive officer’s or key management employee’s responsibilities, as well as the tenure of the executive officer with the Company. Position, geography and economic and market conditions are also considered, particularly with respect to retention. Base salary must be reasonable, fair and competitive. The Committee also considers the historical, current and forecasted performance of the Company and individual operating units, and the contributions or expected contributions of each executive officer or key management employee to those results when considering proposed adjustments to base salary. Salary levels for all executive officers and key management employees are reviewed and typically adjusted annually. Salary levels are also typically reviewed and may be adjusted in connection with a change in job responsibilities.

Annual Cash Incentive Plans. Executive officers and key management employees, including the named executive officers (with the exception of key sales and marketing employees who typically have their own sales incentive or commission plans and from time-to-time certain key employees of newly acquired companies who had or have their own incentive plans), were eligible to receive annual cash payments pursuant to the 2025 Management Incentive Plan (the “2025 Management Incentive Plan”). The Committee has reviewed and approved the 2026 Management Incentive Plan (the “2026 Management Incentive Plan”) with terms that are substantially the same as the 2025 Management Incentive Plan. The 2025 Management Incentive Plan and the 2026 Management Incentive Plan are collectively hereinafter referred to as the “incentive plan.” Target payments under the incentive plan when added to fixed base salary are intended to generate total annual cash compensation that the Company believes is reasonable, fair and competitive with annual cash compensation paid to similarly situated employees at other companies with comparable size and performance.

Incentive plan payments have historically totaled in the aggregate less than 2% of the annual consolidated operating income for the Company. There were approximately 570 participants in the 2025 Management Incentive Plan. Payouts under the 2025 Management Incentive Plan totaled approximately $53 million, representing approximately 0.86% of the Company’s Adjusted Operating Income for 2025. There are currently approximately 690 participants in the 2026 Management Incentive Plan who, at achievement of 100% of 2026 performance targets and goals, would be paid an aggregate of approximately $38 million.

The incentive plan provides participants with a cash bonus if certain operating unit and/or Company goals are achieved. A “responsibility unit” in the discussion below refers to the group or business unit for which the employee has management responsibility or to which he or she is assigned. For executive officers and key management employees with global headquarters roles (i.e., Company-wide responsibilities), such as Messrs. Norwitt and Lampo, the Company is considered the responsibility unit. For Messrs. Walter, Doherty and Straub, the division over which each served as Division President in 2025 is considered the relevant responsibility unit. The incentive plan is intended to reward participants upon the achievement of the goals for their respective responsibility unit, with discretion for qualitative individual, operating unit and Company performance factors. No annual incentive payments will be made if a threshold performance level of profitability is not achieved for the relevant responsibility unit, absent the occurrence of extenuating circumstances that, in the discretion of the Committee, merit an exception to the threshold profitability performance requirement. As a general rule, no incentive plan payment is made to employees with Company- wide responsibilities if Adjusted Diluted EPS declines year-over-year, nor to other employees if the operating income of their respective responsibility unit declines year-over-year.

Incentive plan payment amounts are calculated by multiplying three factors together: (i) a participant’s annual base salary, (ii) a participant’s incentive plan target percentage and (iii) a participant’s incentive plan multiplier. Incentive plan target percentages for each participant are generally established at the beginning of each year.

TABLE OF CONTENTS

The incentive plan multiplier is determined for each participant after the end of each year by analyzing a number of quantitative factors, subject to qualitative adjustment, as discussed in more detail below. The maximum incentive plan multiplier any recipient may be awarded is 200%. The incentive plan does not guarantee any minimum incentive plan multiplier to any participant. For 2025, participants received incentive plan multipliers ranging from 0% to 200%.

A participant’s incentive plan multiplier is based primarily on responsibility unit financial performance against quantitative measures established at the beginning of each year. In addition, adjustments are made, when appropriate, for certain qualitative factors, as well as for reasonableness and consistency. The quantitative portion of the incentive plan multiplier is contingent upon the Company’s achievement and/or the applicable responsibility unit’s achievement of performance targets and/or goals.

	Responsibility Unit Achievement
	Sales Growth		EPS/Operating Income Growth		Incentive Plan Multiplier
Threshold		0%		0%		0%
Target		7%		11%		100%
Maximum		17.5%		27.5%		200%

The Company continues to believe that the key drivers to generating shareholder value are revenue growth, operating income growth and EPS growth. In 2025 the quantitative performance criteria for (i) participants with Company-wide responsibilities was based on Company revenue and Adjusted Diluted EPS growth in 2025 over 2024 and (ii) other participants was based on responsibility unit revenue and operating income growth in 2025 over 2024, adjusted for actual operating income in 2025 as compared to 2025 operating income budget. Revenue growth and operating income growth are calculated on a constant currency basis.

The specific targets to be achieved by Messrs. Norwitt and Lampo to attain a 100% quantitative portion of the incentive plan multiplier in 2025 were (i) Company revenue growth of 7%, and (ii) Company Adjusted Diluted EPS growth of 11%. To achieve a 200% quantitative portion of the incentive plan multiplier in 2025 would have required Company revenue growth of at least 17.5% and Company Adjusted Diluted EPS growth of at least 27.5%. In calculating the incentive plan multiplier, Company revenue growth and Company Adjusted Diluted EPS growth are given equal weighting.

The specific targets to be achieved by Messrs. Walter, Doherty and Straub to attain a 100% incentive plan multiplier under the 2025 incentive plan were (i) responsibility unit revenue growth of 7% and (ii) responsibility unit operating income growth of 11%. In addition, for executives that do not have global headquarters roles, such as Messrs. Walter, Doherty and Straub, the incentive plan multiplier is adjusted up or down based on achievement to operating income budget. To achieve a 200% quantitative portion of the incentive plan multiplier under the incentive plan in 2025 would have required responsibility unit revenue growth of at least 17.5% and responsibility unit operating income growth of at least 27.5%. In calculating the incentive plan multiplier, responsibility unit operating income growth and responsibility unit revenue growth are given equal weighting.

If Adjusted Diluted EPS or operating income, as applicable, decline, the impact to the incentive plan multiplier is at the discretion of the Committee, but generally has resulted in an overall incentive plan multiplier of 0%.

Once the quantitative portion of the incentive plan multiplier is established, management and/or the Committee, as applicable, consider various qualitative factors and may adjust the incentive plan multiplier accordingly. The qualitative analysis is designed to ensure that a participant is rewarded for responsibility unit performance and individual performance, but also to provide a means to ensure the awards are fair and meet the other goals of the Committee in determining executive compensation. The qualitative portion of the incentive plan may include one or more of the following factors: whether operating margins of the responsibility unit are above or below the average of the Company, balance sheet management including cash flow, operating unit and group contribution to total Company performance, risk management issues,

TABLE OF CONTENTS

contributions of responsibility unit to achieving the Company’s sustainability goals, industry performance, special market conditions, budget impact and any other factor that the Committee deems relevant under the circumstances.

In 2026 there is no change in the quantitative performance criteria for the 2026 Management Incentive Plan as compared to the 2025 Management Incentive Plan.

Stock Option Plans. In May 2017, stockholders approved and the Company adopted the 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the “Original 2017 Option Plan”) and in May 2021, stockholders approved and the Company adopted the Amended and Restated 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (together with the Original 2017 Option Plan, the “2017 Option Plan”). Granting stock options is a simple and clear means to maintain the alignment of the interests of the Company’s executive officers and key management employees with its stockholders and allows executive officers and key management employees to participate in the long-term value creation of the Company. The Committee believes that granting stock options helps create competitive levels of compensation and provides an opportunity for increased equity ownership by executive officers and key management employees (including the named executive officers). All currently outstanding employee stock option grants have a five-year vesting period, with 20% vesting each year. The Committee believes this extended vesting schedule improves retention of executive officers and key management employees while encouraging them to make decisions that achieve a healthy balance between short- and long-term Company performance. The total expense for options granted each year is typically in the range of approximately 3% to 5% of the Company’s annual budgeted consolidated operating income for such year.

The employee stock option plan is administered by the Committee. The Committee will consider recommendations of the Chief Executive Officer and other senior management employees of the Company and determine those employees of Amphenol and its subsidiaries who will be eligible to receive options, the number and the terms and conditions of each option grant, the form of the option agreement and any conditions on the exercise of an option award. For more information on equity grant practices and procedures, including with respect to the timing of awards of stock options, see the section entitled Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information beginning on page 62.

In determining the number of options to be granted to an individual employee, a value is imputed for each option, with reference to the Company’s then current stock price and the Black-Scholes valuation of each option granted. The Committee also considers information regarding the total amount of options available, an individual’s base salary, the amount of stock options, if any, previously awarded to an individual, an individual’s past and expected future contributions to the Company’s financial performance and an individual’s responsibilities for assisting the Company in achieving its long-term strategic goals. The Committee also considers the estimated dilutive effect of options granted each year.

Insurance Benefits. Each executive officer and key management employee (including the U.S.-based named executive officers) is offered the same health and life insurance benefits as other employees working at the same location. The Company also makes a contribution to group term life insurance on behalf of substantially all U.S.-based salaried employees (including the U.S.-based named executive officers) on the same terms and conditions as similarly situated U.S.-based salaried employees for which the Company is required to impute compensation for amounts in excess of $50,000 net of employee payments, see table of All Other Compensation under footnote (4) on page 44. Key management employees outside of the U.S. participate in the same insurance programs on the same terms and conditions as similarly situated salaried employees.

Retirement Benefits. U.S.-based salaried employees (including the U.S.-based named executive officers) may participate in the Company’s Pension Plan, Supplemental Employee Retirement Plan, or SERP, a non-qualified supplemental defined contribution program, or DC SERP, and in the Company’s 401(k) programs on the same terms and conditions as similarly situated U.S.-based salaried employees. For more information on the Pension Plan, the SERP, the DC SERP and 401(k) programs, and each named executive officer’s participation, see the section entitled Pensions and Deferred Compensation beginning on page 48. As certain of the retirement programs are unfunded, i.e., the SERP and the DC SERP, the Company’s executives are incentivized to look after the long-term health of the Company. Key management employees outside of the U.S. participate in the same retirement programs on the same terms and conditions as similarly situated salaried employees.

Mr. Norwitt continues to receive car and driver and security-related services in 2026. No other perquisites were provided to the named executive officers in 2025 or are planned in 2026.

Compensation of Named Executive Officers

Company Performance — When determining compensation, the Committee reviewed the Company’s 2025 financial results. The Company’s 2025 financial results were prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and reported in the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “Company’s 2025 Annual Report”). In addition to reviewing relevant GAAP financial measures, the Committee considered non-GAAP measures which it believes are also relevant in gauging year-over-year performance. Thus, Constant Currency Net Sales Growth, Adjusted Operating Income and Adjusted Diluted EPS and other non-GAAP measures are referenced in this proxy statement.2

In 2025, the Company achieved net sales of $23.1 billion, representing an increase of 52% in U.S. Dollars and 51% in constant currencies as compared to 2024. For the years ended December 31, 2025 and 2024, GAAP Diluted EPS was $3.34 and $1.92, respectively. GAAP Diluted EPS in 2025 included (i) excess tax benefits of $246.6 million ($0.19 per share) related to stock-based compensation resulting from stock option exercises, (ii) a discrete tax expense of $100 million ($0.08 per share) and (iii) acquisition-related expenses of $181.2 million ($148.8 million after-tax, or $0.12 per share). GAAP Diluted EPS in 2024 included (i) excess tax benefits of $142.6 million ($0.11 per share) related to stock-based compensation resulting from stock option exercises, (ii) a discrete tax benefit of $18.6 million ($0.01 per share) and (iii) acquisition-related expenses of $145.6 million ($119.3 million after-tax, or $0.09 per share). Excluding these items, Adjusted Diluted EPS in 2025 was $3.34, as compared to $1.89 in 2024, representing an increase of 77%.

The non-GAAP financial measures defined below should be read in conjunction with the Company’s financial statements presented in accordance with GAAP. See Part II, Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Company’s 2025 Annual Report for further details. Non-GAAP financial measures related to net sales exclude the impact of foreign currency exchange rates. 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 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.

•

Adjusted Diluted EPS is defined as diluted earnings per share (as reported in accordance with 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.

•

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

(2) Explanation of Non-GAAP Financial Measures. In addition to assessing the Company’s financial condition, results of operations, liquidity and cash flows in accordance with GAAP, management and the Committee utilize certain non-GAAP financial measures defined below when assessing employee compensation measures. Management and the Committee believe 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.

expenses and their specific tax effects that are not directly related to the Company’s operating performance during the years presented.

•

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.

•

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).

•

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 Constant Currency Net Sales Growth, and believes that such information is useful to investors to assess the underlying sales trends.

•

Free Cash Flow is defined as (i) Net cash provided by operating activities (“Operating Cash Flow” — as reported in accordance with GAAP) less (ii) capital expenditures (as reported in accordance with GAAP), net of proceeds from disposals of property, plant and equipment (as reported in accordance with 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.

Refer to Part II, Item 7 of the Company’s 2025 Annual Report for definitions and reconciliations of non-GAAP financial measures to their most directly comparable GAAP financial measures.

Pay Mix — Compensation programs for the named executive officers emphasize at-risk, performance- based elements geared to encourage management to generate long-term shareholder value, namely stock options and annual incentive plan compensation linked to goals that encourage growth in revenue, operating income and/or Adjusted Diluted EPS. Fixed compensation elements, such as base salary, retirement benefits and other compensation are designed to be market competitive for purposes of retention, and to a lesser extent, recruitment.

TABLE OF CONTENTS

of his total 2025 compensation. These at-risk elements include stock options granted with an exercise price equal to the closing price of the Company’s Common Stock on the date of grant which only generate value if the Company’s share price increases after the grant date. The value ascribed to the options for purposes of calculating percentages in this paragraph is the grant date fair value calculated in accordance with ASC Topic 718, as further described in footnote (1) to the Summary Compensation Table on page 43. The other at-risk compensation is annual incentive-plan compensation which historically has not paid out if Adjusted Diluted EPS declines, and rewards the Chief Executive Officer when Company revenues and Adjusted Diluted EPS grow. For the Company’s other named executive officers as a group, fixed compensation elements comprised approximately 15% of total 2025 compensation while at-risk compensation comprised approximately 85% of total 2025 compensation. As with the Chief Executive Officer, the fixed compensation elements for the other named executive officers include salary and “all other compensation,” while the at-risk items include stock options and annual incentive plan compensation linked to goals that encourage growth in revenues and either Adjusted Diluted EPS or operating income, depending on the role of the named executive officer.

2025 Management Incentive Plan Determination. As described in the section entitled Annual Cash Incentive Plans above, the incentive plan multiplier is based primarily on responsibility unit financial performance. The Company continues to believe that the key drivers to generating shareholder value are revenue growth, operating income growth and EPS growth. In 2025 the quantitative performance criteria for (i) participants with global headquarters roles was based on Company revenue and Adjusted Diluted EPS growth in 2025 over 2024 and (ii) other participants was based on responsibility unit revenue and operating income growth in 2025 over 2024, adjusted for actual responsibility unit operating income in 2025 as compared to responsibility unit operating income budget. For 2025, the budgeted operating income performance adjustment did not impact the final incentive plan multiplier for any of Messrs. Walter, Doherty or Straub. Revenue growth and operating income growth are calculated on a constant currency basis for all participants. Based on the above, the incentive plan multipliers for our named executive officers in 2025 were determined as follows:

	Responsibility Unit Achievement*						Incentive Plan Multiplier
	Constant Currency Net Sales Growth		Adjusted Diluted EPS Growth		Adjusted Operating Income Growth		Incentive Plan Multiplier
Guidelines
Threshold		0%		0%		0%		0%
Target		7%		11%		11%		100%
Maximum		17.5%		27.5%		27.5%		200%

CEO Compensation. In January 2026, Mr. Norwitt’s annual base salary was increased by approximately 5.4% from $1,565,000 to $1,650,000. Mr. Norwitt’s annual incentive plan target percentage pursuant to the 2026 Management Incentive Plan was increased from 180% to 200%. In its deliberations about whether and how to adjust these two elements of Mr. Norwitt’s compensation, the Committee considered the Company’s financial performance in 2025, including in particular the significant growth in net sales and Adjusted Diluted EPS from prior year, as well as annual base salary and target bonus percentages of chief executive officers of similarly sized companies based on information provided by Meridian.

TABLE OF CONTENTS

Based on calculations described in the section entitled Annual Cash Incentive Plans above, the quantitative portion of Mr. Norwitt’s incentive plan multiplier in 2025 was calculated to be 200%, the same percentage calculated for all named executive officers and key management employees with global headquarters roles. His incentive plan payment pursuant to the 2025 Management Incentive Plan was therefore $5,634,000, representing a product of his 2025 base salary of $1,565,000 multiplied by his incentive plan target percentage of 180%, multiplied by the global headquarters incentive plan multiplier of 200%. This was the maximum possible payout under the 2025 Management Incentive Plan.

In May 2025, Mr. Norwitt was awarded 602,344 options pursuant to the 2017 Option Plan with an exercise price of $86.88 and a grant date value of $14,649,006. The option award reflects the Board’s confidence in his leadership and is designed to further align Mr. Norwitt’s interests with the Company’s stockholders to generate long-term shareholder value. In granting this award to Mr. Norwitt, the Committee considered the Company’s ongoing substantial growth in the scale and complexity of the Company during Mr. Norwitt’s tenure as well as the importance of closely aligning Mr. Norwitt’s interests with those of the Company’s stockholders.

In 2025, Mr. Norwitt was provided with car and driver and security-related services. The Company expenses associated with the car and driver were $15,694. The Company expenses associated with the security- related services were $9,631. The imputed value of compensation for group term life insurance provided to Mr. Norwitt in 2025 in excess of $50,000, net of employee payments, was $10,062. The Company continues to provide Mr. Norwitt with car and driver and security-related services and to contribute to his group term life insurance in 2026.

Mr. Norwitt continues to participate in the Pension Plan (further described in the section entitled Pension Plan Background commencing on page 48), but his benefits under such Pension Plan were frozen effective December 31, 2006. In 2025, Mr. Norwitt received a 401(k) match of $22,250. The Company made notational contributions to a non-qualified supplemental defined contribution plan, or DC SERP, on behalf of Mr. Norwitt for 2025 of $435,445. Mr. Norwitt continues to participate in the 401(k) Plan and the DC SERP in 2026.

Other Named Executive Officers’ Compensation. For each of the other named executive officers, in determining annual cash incentive plan payments and stock option awards for 2025, and base salary and incentive plan target adjustments for 2026, the Committee considered each executive’s overall performance, as well as relevant market data from Meridian. In the case of Mr. Lampo, the Committee evaluated the overall performance of the Company and his contributions to that performance. In the case of Messrs. Walter, Doherty and Straub, the Committee evaluated their contributions to the performance and results of the division over which each served as Division President.

Mr. Lampo. In January 2026, Mr. Lampo’s annual base salary was increased by approximately 13% from $730,000 to $825,000, to reflect a market adjustment for the increased size and complexity of the Company’s business and his promotion to Executive Vice President.

Based on calculations described in the section entitled Annual Cash Incentive Plans above, the quantitative portion of Mr. Lampo’s incentive plan multiplier in 2025 was calculated to be 200%, the same percentage calculated for all named executive officers and key management employees with global headquarters roles. His incentive plan payment pursuant to the 2025 Management Incentive Plan was therefore $1,460,000, representing a product of his 2025 base salary of $730,000 multiplied by his incentive plan target percentage of 100%, multiplied by the global headquarters incentive plan multiplier of 200%. This was the maximum possible payout under the 2025 Management Incentive Plan.

Mr. Lampo’s incentive plan target percentage pursuant to the 2026 Management Incentive Plan was increased from 100% to 110% of his base salary, which represents a continued emphasis on performance-based compensation. This variable, at-risk compensation is designed to incentivize performance in line with the core goal of increasing revenue and profit growth for the Company.

In May 2025, Mr. Lampo was awarded 172,496 options pursuant to the 2017 Option Plan with an exercise price of $86.88 and a grant date value of $4,195,103.

TABLE OF CONTENTS

Mr. Walter. In January 2026, Mr. Walter’s annual base salary was increased by approximately 4.3% from $815,000 to $850,000, in line with the average increase generally given to other salaried employees of the Company in the United States.

Based on calculations described in the section entitled Annual Cash Incentive Plans above, Mr. Walter’s payment pursuant to the 2025 Management Incentive Plan was $1,304,000, representing the product of his 2025 base salary of $815,000 multiplied by his incentive plan target percentage of 80%, multiplied by his incentive plan multiplier of 200%. This was the maximum possible payout under the 2025 Management Incentive Plan.

Mr. Walter’s incentive plan target percentage pursuant to the 2026 Management Incentive Plan was increased from 80% to 85% of his base salary, which represents a continued emphasis on performance-based compensation. This variable, at-risk compensation is designed to incentivize performance in line with the core goal of increasing revenue and operating income growth within Mr. Walter’s division.

In May 2025, Mr. Walter was awarded 146,824 options pursuant to the 2017 Option Plan with an exercise price of $86.88 and a grant date value of $3,570,760.

He also continues to participate in the 401(k) Plan and the DC SERP in 2026.

Mr. Doherty. In January 2026, Mr. Doherty’s annual base salary was increased by approximately 8.7% from $750,000 to $815,000, to reflect a market adjustment for the increased size and complexity of the Communications Solutions division.

Based on calculations described in the section entitled Annual Cash Incentive Plans above, Mr. Doherty’s payment pursuant to the 2025 Management Incentive Plan was $1,200,000, representing the product of his 2025 base salary of $750,000 multiplied by his incentive plan target percentage of 80%, multiplied by his incentive plan multiplier of 200%. This was the maximum possible payout under the 2025 Management Incentive Plan.

Mr. Doherty’s incentive plan target percentage pursuant to the 2026 Management Incentive Plan was increased from 80% to 85% of his base salary, which represents a continued emphasis on performance-based compensation.

TABLE OF CONTENTS

Mr. Straub. In January 2026, Mr. Straub’s annual base salary was increased by approximately 5% from $600,000 to $630,000, slightly higher than the average increase generally given to other salaried employees of the Company in the United States due to the increased size and complexity of the Interconnect and Sensor Systems division.

Based on calculations described in the section entitled Annual Cash Incentive Plans above, Mr. Straub’s payment pursuant to the 2025 Management Incentive Plan was $912,000, representing the product of his 2025 base salary of $600,000 multiplied by his incentive plan target percentage of 80%, multiplied by his incentive plan multiplier of 190%. This is compared to a maximum possible payout under the 2025 Management Incentive Plan of $960,000.

Mr. Straub’s incentive plan target percentage pursuant to the 2025 Management Incentive Plan was increased from 80% to 85% of his base salary, which represents a continued emphasis on performance-based compensation.

In 2006, the Company amended its Pension Plan by freezing accruals effective December 31, 2006 for certain personnel below the age of 50 and/or with certain years of service with the Company. Simultaneously, the Company implemented employer contributions to the Amphenol 401(k) Plan and to a related non-qualified supplemental defined contribution plan, or DC SERP, for those same individuals and for certain new hires. Beginning in 2007, Messrs. Norwitt, Lampo and Walter no longer accrue any additional benefits under the Pension Plan. In 2025, there was an increase in pension values for Messrs. Norwitt, Lampo and Walter of $10,200, $3,000 and $2,100, respectively, because of changes in actuarial assumptions in 2025 as compared to 2024; in 2024, there was a decrease in pension values for Messrs. Norwitt, Lampo and Walter of $5,100, $1,600 and $44,000, respectively, because of changes in actuarial assumptions in 2024 as compared to 2023; and in 2023, there was an increase in pension values for Messrs. Norwitt, Lampo and Walter of $8,800, $2,600 and $24,200, respectively, because of changes in actuarial assumptions in 2023 as compared to 2022. Notwithstanding that their pension benefits were frozen effective December 31, 2006, the value of the frozen benefits fluctuates as related actuarial assumptions change. The changes in pension value in each case represent the increase and decrease, respectively, in the actuarial present value of their respective benefits under the Pension Plan. For years in which changes in actuarial assumptions result in a decrease in pension value, rather than report a negative number, a change of $0 is reported. Messrs. Doherty and Straub do not participate in the Pension Plan.

The amounts reported for Mr. Norwitt in 2025 include monitoring expenses associated with a home security system at his residence.

(6)

The amount reported for Mr. Straub in 2025 includes (i) $22,250 in Company contributions under its 401(k) plan, received on the same terms and conditions as similarly situated U.S.-based salaried employees, and (ii) a separate Company contribution of $9,100 as compensation for the discontinuation of a pension plan in which Mr. Straub was a participant while employed at a company previously acquired by Amphenol.

Section 162(m) of the Internal Revenue Code

Section 162(m) of the Code places a limit of $1,000,000 per person on the amount of compensation that a public company may deduct in any year with respect to certain current or former executive officers. The Compensation Committee believes that stockholder interests are best served by not restricting the Committee’s flexibility in structuring compensation plans, even though such plans may result in non-deductible compensation expenses. Accordingly, achieving the desired flexibility in the design and delivery of compensation may result in compensation that in certain cases is not deductible for U.S. federal income tax purposes.

Employment Agreements

In conjunction with accepting each stock option award, all option award recipients, including each of the named executive officers, becomes party to a stock option agreement with the Company which contemplates, among other things, that a terminated employee may be paid, at the Company’s discretion, fifty percent of base salary in the form of salary continuation following his/her termination for up to two years, in exchange for a firm undertaking from the terminated employee not to compete with the business of the Company.

Pursuant to an employment letter agreement with the Company dated March 22, 1999, the Company has agreed that if Mr. Walter is terminated by the Company without cause, the Company is obligated to (i) pay him lump sum severance equal to 100% of the base compensation he received in the twelve-month period preceding his termination and (ii) relocate him to France if he so chooses.

Except as set forth above, none of the named executive officers are parties to any employment agreements with the Company.

Stock Option Plans

In May 2017, stockholders approved and the Company adopted the 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the “Original 2017 Option Plan”) and in May 2021,

TABLE OF CONTENTS

stockholders approved and the Company adopted the Amended and Restated 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (together with the Original 2017 Option Plan, the “2017 Option Plan”). While 675,203 options remain outstanding as of the Record Date under the 2009 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries, as amended (the “2009 Option Plan”), the Company ceased granting options under the 2009 Option Plan at the time the 2017 Option Plan was adopted. The 2009 Option Plan and the 2017 Option Plan are collectively referred to herein as the “Company’s Option Plans.” The Company’s Option Plans provide for the granting of an option to purchase shares not intended or not qualifying as an incentive stock option as defined in Section 422 of the Internal Revenue Code.

No options can be granted at less than the fair market value of the Company’s Common Stock on the date of the grant. The Company is not able to grant any restricted stock awards, stock appreciation rights, dividend equivalent rights, performance units, performance shares or any other stock-based grants other than non-qualified options under the Company’s Option Plans, and stockholder approval is required for any material amendments. Option awards vest in equal annual installments over a five-year period and have a ten-year term. In the event of a death or disability (as defined in the plans), assuming the minimum service requirements have been satisfied, a participant will immediately vest in all outstanding options. The Compensation Committee has discretion to allow continued vesting of unvested options following termination of employment due to retirement at age 65 or older with at least five years of employment with the Company or following termination of employment due to retirement at age 55 or older with at least ten years of employment with the Company. Vesting stops under most other termination situations.

A total of 7,900,943 options were granted under the 2017 Option Plan on May 16, 2025 at an exercise price of $86.88 to approximately 1,170 employees of the Company including the named executive officers. An aggregate of 390,360 options at exercise prices ranging from $69.01 to $141.55 were also granted under the 2017 Option Plan at other times in 2025 to other employees. There are 84,103,522 options outstanding as of the Record Date under the 2017 Option Plan, and of the 200,000,000 shares of Common Stock reserved for issuance pursuant to the 2017 Option Plan, 47,395,324 shares are available for future option grants as of the Record Date. The 2017 Option Plan limits the number of options that may be granted to any one participant in any fiscal year to not more than 6,000,000 options, which may be doubled during the first fiscal year a participant commences employment with the Company and/or its subsidiaries.

Repricing of Options/Granting of SARs

During the last fiscal year, the Company did not reprice any options nor did it grant any SARs. The Company’s Option Plans do not provide for the granting of SARs or any other stock-based grants.

PENSIONS AND DEFERRED COMPENSATION

Pension Plan

Pension Plan Background. Certain employees of the Company and its U.S. subsidiaries are eligible to participate in the Pension Plan for Employees of Amphenol Corporation, referred to as the Pension Plan, which is a defined benefit pension plan. Benefits are calculated based on the section of the Pension Plan in which an employee participates. The Company also sponsors a supplemental employee retirement plan (the “SERP”) which provides for the payment of the portion of an annual pension which cannot be paid from the Pension Plan as a result of limitations contained in the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).

In 2006, the Company amended the Pension Plan by freezing accruals effective December 31, 2006 for personnel with less extensive service (referred to as the “non-grandfathered participants”). In connection with the freezing of accruals under the Pension Plan, beginning in 2007, the Company implemented employer contributions to the Amphenol 401(k) Plan and to a related non-qualified supplemental defined contribution plan for non-grandfathered participants and certain new employees of the Company and its U.S. subsidiaries. Grandfathered participants will continue to accrue incremental benefits under the Pension Plan and the SERP and will continue to be eligible to participate in the Amphenol 401(k) plan with no employer contributions.

Messrs. Doherty and Straub do not participate in the Pension Plan or the SERP. Mr. Lampo participates in the Pension Plan but not the SERP. The other named executive officers participate in the Pension Plan and the SERP as non-grandfathered participants. Non-employee directors do not participate in the Pension Plan, although Mr. Loeffler participated in the Pension Plan and the SERP during his prior employment with the Company.

General Provisions of the Pension Plan. The normal retirement date under the Pension Plan is the first day of the month following a participant’s 65th birthday. A participant may also retire as of the first day of any month subsequent to the participant’s 55th birthday and completion of either five or ten years of service; however, a participant’s normal retirement benefit is reduced by as much as 50% if payment of retirement benefits commences upon early retirement. Retirement benefits are paid in the form of a life annuity (generally a reduced joint and survivor annuity for married participants). The Company has a policy that prohibits granting extra years of credited service under the Pension Plan.

For the section of the Pension Plan in which Mr. Norwitt participated, the annual normal retirement benefit is equal to the greater of: (i) 1.1% of the participant’s final average pensionable compensation multiplied by the participant’s years of credited service or (ii) 1.8% of the participant’s final average pensionable compensation multiplied by the participant’s years of credited service not in excess of 25 (1% for years in excess of 25) reduced by 2% of the participant’s estimated annual social security benefit multiplied by the participant’s years of credited service not in excess of 30. Average pensionable compensation is equal to the participant’s average annual total compensation, excluding bonuses and incentive plan payments, during the three years prior to the Pension Plan being frozen.

For the section of the Pension Plan in which Messrs. Lampo and Walter participated, the annual normal retirement benefit is equal to the greater of: (i) 2% of the participant’s final average pensionable compensation multiplied by the participant’s years of credited service not in excess of 25 less 2% of the participant’s estimated

TABLE OF CONTENTS

annual social security benefit multiplied by the participant’s years of credited service not in excess of 25 or (ii) 1.5% of average pensionable compensation multiplied by credited service not in excess of 15 years. Average pensionable compensation is equal to the participant’s average annual compensation, including bonuses and incentive payments, during the five years immediately prior to the Pension Plan being frozen.

Mr. Walter’s Retirement Benefit Assuming He Elects Normal Retirement. Mr. Walter meets the age and service requirements for normal retirement under his section of the Pension Plan. If Mr. Walter were to have elected retirement as of December 31, 2025, he could have elected to receive his accrued benefit starting immediately. The benefit would be equal to $2,449 per month payable from the Pension Plan and $2,788 per month payable from the SERP.

Mr. Norwitt’s Retirement Benefit Assuming He Elects Early Retirement. During 2025, Mr. Norwitt met the age and service requirements for early retirement under his section of the Pension Plan. If Mr. Norwitt were to have elected retirement as of December 31, 2025, he could have elected to receive his accrued benefit starting immediately. The benefit would be equal to $460 per month payable from the Pension Plan and $153 per month payable from the SERP.

Mr. Lampo’s Retirement Benefit Assuming He Elects Early Retirement. During 2025, Mr. Lampo met the age and service requirements for early retirement under his section of the Pension Plan. If Mr. Lampo were to have elected retirement as of December 31, 2025, he could have elected to receive his accrued benefit starting immediately. The benefit would be equal to $179 per month payable from the Pension Plan.

Credited service was frozen as of December 31, 2006 for Messrs. Norwitt, Lampo and Walter.

(2)

Computed as of December 31, 2025, the same Pension Plan measurement date used for financial statement reporting purposes with respect to the Company’s audited 2025 financial statements. Calculation of present value reflects FASB ASC Topic 715, “Compensation Retirement Benefits,” disclosure assumptions described in Note 9 — Benefit Plans and Other Postretirement Benefits to the Company’s 2025 Annual Report.

(3)

Although Mr. Norwitt had been employed with the Company or its subsidiaries for approximately eight years when his credited service was frozen, he has only 3.0 years of credited service in the Pension Plan and the SERP. Prior to becoming directly employed by Amphenol Corporation and joining the Pension Plan and the SERP, Mr. Norwitt was employed by Amphenol East Asia Limited, a Hong Kong subsidiary of the Company.

(4)

Although Mr. Walter had been employed with the Company or its subsidiaries for approximately 23 years when his credited service was frozen, he has only 8.0 years of credited service in the Pension Plan and the SERP. Prior to becoming directly employed by Amphenol Corporation and joining the Pension Plan and the SERP, Mr. Walter was employed by Amphenol Socapex SAS, a French subsidiary of the Company.

(5)

Messrs. Doherty and Straub do not participate in the Pension Plan or the SERP.

Pension Plan and 401(k) Plan. Beginning on January 1, 2007, non-grandfathered participants in the Pension Plan, including Messrs. Norwitt, Lampo and Walter, and most U.S.-based employees who were not participants in the Pension Plan as of December 31, 2006, including Mr. Doherty and Mr. Straub, have been provided a Company contribution to their Company qualified 401(k) savings plan (the “Amphenol 401(k) Plan”) accounts. In 2025, the Company contribution was equal to 3% of their covered earnings (for which no employee contribution is required) and in addition, the Company matched 50% of the employee’s first 8% contribution of their covered earnings. Covered earnings include base salary and incentive plan compensation.

TABLE OF CONTENTS

The Company also sponsors a non-qualified supplemental defined contribution plan (the “DC SERP”) for selected non-grandfathered participants in the Amphenol 401(k) Plan. Each of our named executive officers participates in the DC SERP. Participants in the DC SERP are credited with an 8% employer contribution on compensation in excess of the limitations imposed by the Internal Revenue Code. Each participating named executive officer is also permitted to defer up to 8% of his estimated compensation in excess of the limitations imposed by the Internal Revenue Code to a DC SERP account. A participant may elect to defer base salary and non-equity incentive plan compensation under the DC SERP and a participant’s election to defer compensation is made prior to the beginning of each year and is binding for the applicable year. The participant concurrently selects the timing of the distribution of their deferred compensation. Distributions may occur upon termination of employment (which could include retirement, death or disability) or upon a specified future date while still employed (an “in-service distribution”), as elected by the participant. For the named executive officers, any distribution payable on account of termination of employment will not occur until after six months following termination of employment pursuant to Section 409A of the Internal Revenue Code. Compensation deferred by participants and any matching contributions made by the Company are credited to a bookkeeping account that represents the Company’s unsecured obligation to repay the participant in the future.

TABLE OF CONTENTS

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The amount of compensation that may be payable to each named executive officer upon voluntary termination, early retirement, normal retirement, involuntary not-for-cause termination, for-cause termination, termination following a change of control and in the event of disability or death of the executive is shown on the tables on pages 53-55. The amounts shown assume that such termination was effective as of December 31, 2025, and thus include amounts earned through such time and are estimates of the amounts which could have been paid out to the named executive officers in connection with their termination. The actual amounts to be paid can only be determined in the event of and at the time of such executive’s separation from the Company.

Payments Made Upon Termination. Regardless of the manner in which a named executive officer’s employment is terminated, he or she is entitled to receive amounts earned during his or her term of employment. Such amounts might include:

•

unused vacation pay;

•

amounts accrued and vested through the Company’s retirement plans;

•

statutory entitlements; and

•

non-equity incentive compensation relating to the fiscal year.

Payments Made Upon Retirement. The plan administrator (currently the Compensation Committee) has the discretion to decide if options will continue to vest following normal retirement at age 65 with at least five years of employment with the Company or upon early retirement at or after age 55 with more than 10 years of employment with the Company. Mr. Walter is currently eligible for normal retirement. Messrs. Doherty, Norwitt, Lampo and Straub are currently eligible for early retirement.

Payments Made Upon Involuntary Not for Cause Termination or Involuntary for Good Reason Termination. In the event of involuntary not for cause termination or involuntary for good reason termination of any employee, including a named executive officer, in addition to the benefits which might be made as reflected under the heading Payments Made Upon Termination above, the Board has the discretion to decide if options that are not vested at the time of such termination shall vest and the terms of such vesting. The disclosure in the tables below for involuntary not for cause termination and involuntary for good reason termination assumes that the Board has exercised its discretion to continue vesting of all such options.

Payments Made Upon a Change in Control. Pursuant to the 2009 Option Plan, immediately prior to a change in control (as defined in the plan), all outstanding options held by any employee, including a named executive officer, immediately vest and become exercisable at the discretion of the Board. Pursuant to the 2017 Option Plan, the plan administrator (currently the Compensation Committee) has discretion to accelerate options upon a change in control (as defined in the plan). The disclosure in the tables below relating to change in control assumes that the Board has exercised its discretion to cause all shares to vest.

Payments Made Upon Death or Disability. In the event of the death or disability of any employee, including a named executive officer, in addition to the benefits which might be made as reflected under the heading Payments Made Upon Termination above, he or she may receive benefits and/or payments under the group term life insurance plan and/or the Company funded disability plan, as appropriate. In the event of death or disability as defined in the Company’s Option Plans, assuming the minimum service requirements have been satisfied, all outstanding options held by such individual will immediately vest. The disclosure in the tables below reflects that the minimum service requirements for all named executive officers have been satisfied.

Health Care Benefits. The Company does not currently offer any of the named executive officers any enhanced health care benefits on termination for any reason.

(1)

This is the amount actually paid to Mr. Norwitt in January 2026 pursuant to the 2025 Management Incentive Plan. Assuming a termination event as of December 31, 2025, this amount would only have been paid upon approval by the Compensation Committee.

(2)

Each of the named executive officers is a party to stock option agreements with the Company which contemplate, among other things, that a terminated employee may be paid fifty percent of base salary following his/her termination, at the Company’s discretion, for up to two years, in exchange for a firm undertaking from the terminated employee not to compete with the business of the Company. Mr. Norwitt’s base salary at December 31, 2025 was $1,565,000. Payments are made in the form of salary continuation.

(3)

The Company funds a short-term disability benefit that provides salary continuation for up to six months for most of its U.S. salaried employees. The potential payout of $782,500 is based on Mr. Norwitt’s base salary at December 31, 2025 and assumes the maximum possible amount is paid, i.e., 100% of base salary for a six-month period.

(4)

Upon the occurrence of certain triggering events, all unvested options may vest. The indicated amounts under all columns represent the net value (i.e., the excess of the fair market value of the stock minus the exercise price of an option) of all unvested options as of December 31, 2025 based on the closing price of the Company’s Common Stock on the New York Stock Exchange (“NYSE”) of $135.14 on December 31, 2025.

This is the amount actually paid to Mr. Lampo in January 2026 pursuant to the 2025 Management Incentive Plan. Assuming a termination event as of December 31, 2025, this amount would only have been paid upon approval by the Compensation Committee.

Each of the named executive officers is a party to stock option agreements with the Company which contemplate, among other things, that a terminated employee may be paid fifty percent of base salary following his/her termination, at the Company’s discretion, for up to two years, in exchange for a firm undertaking from the terminated employee not to compete with the business of the Company. Mr. Lampo’s base salary at December 31, 2025 was $730,000. Payments are made in the form of salary continuation.

(3)

The Company funds a short-term disability benefit that provides salary continuation for up to six months for most of its U.S. salaried employees. The potential payout of $365,000 is based on Mr. Lampo’s base salary at December 31, 2025 and assumes the maximum possible amount is paid, i.e., 100% of base salary for a six-month period.

(a)

In 2006, the Company amended its Pension Plan by freezing accruals effective December 31, 2006 for certain employees, including three of our 2025 NEOs that participated in the Pension Plan, Messrs. Norwitt, Lampo and Walter. Messrs. Doherty and Straub do not participate in the Pension Plan. In 2025, there was an increase in pension values for Messrs. Norwitt, Lampo and Walter because of changes in actuarial assumptions in 2025 as compared to 2024. Notwithstanding that their pension benefits were frozen in 2006, the value of the frozen benefits fluctuates as related actuarial assumptions change.

(b)

Because the Pension Plan has been frozen for each of our participating NEOs since 2006, the reportable service cost for 2025 is $0.

Pay Versus Performance Tabular List

We believe the following performance measures represent the most important financial performance measures used by us to link compensation actually paid to our NEOs for the fiscal year ended December 31, 2025:

For our CEO and CFO			For our Division Presidents
Net Sales Growth for the Company			Net Sales Growth for the relevant Division
Adjusted Diluted EPS Growth			Adjusted Operating Income Growth for the relevant Division Performance to Budget for the relevant Division

For additional details regarding our most important financial performance measures, please see Annual Cash Incentive Plans in the Compensation Discussion and Analysis on page 33 and see Explanation of Non- GAAP Financial Measures on page 36 to see items excluded.

CEO PAY RATIO

As required by Section 953(b) of the Dodd Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Mr. Norwitt, President and CEO (the “CEO”).

The Company is a vertically integrated manufacturer with extensive labor-intensive operations in numerous low-cost countries. As of December 31, 2025, we estimate that our employee population consisted of approximately 170,000 individuals globally, with a majority of those employees based in low-cost countries. The Company’s disclosed ratio may be higher relative to other companies which rely more heavily on outsourced production or otherwise source products and components from low-cost countries without operating their own manufacturing facilities. We believe our compensation levels are competitive with prevailing wage rates in the local markets in which we operate.

In 2025, the Company concluded that there were not any changes in the employee population or our compensation practices that would significantly affect our pay ratio disclosure and, consequently, that no change to the employee identified at the median compensation level of the Company as identified in our 2024 compensation analysis (the “Median Employee”) was warranted.

TABLE OF CONTENTS

For 2025, the total annual compensation (determined in accordance with the summary compensation table rules) of our Median Employee, who was a direct labor employee in one of our China plants, was $18,816 (based on the average US dollar to RMB exchange rate for 2025 of 0.1392 as reported by Bloomberg).

In addition, for 2025, the total annual compensation for the employee identified at the median compensation level of US based employees of the Company (the “Median US Employee”) was $66,799 (determined in accordance with the summary compensation table rules).

For 2025, our last completed fiscal year, annual total compensation of the CEO for purposes of determining the CEO Pay Ratio was $22,351,288.

Based on this information, for 2025, the ratio of the annual total compensation of the CEO to the annual total compensation of the Median Employee is estimated to be 1188:1 and the ratio of the annual total compensation of the CEO to annual total compensation of the Median US Employee is estimated to be 335:1.

The pay ratios above are reasonable estimates calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodologies described below. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above as other companies may have different employment and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Moreover, there are a number of factors which make a meaningful comparison of pay ratios difficult, such as industry specific pay differentials, the geographic location of employee populations and a company’s manufacturing strategy (e.g., outsourcing versus insourcing).

PROPOSAL 3. ADVISORY VOTE TO APPROVE
COMPENSATION OF NAMED EXECUTIVE OFFICERS

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended, the Board is asking stockholders to approve the following advisory resolution at the 2026 Annual Meeting:

RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion is hereby APPROVED.

The Board recommends a vote FOR this resolution because it believes that the compensation policies and practices of the Company described in the Compensation Discussion and Analysis have been and continue to be effective in helping to achieve the Company’s goals of rewarding sustained financial and operating performance and leadership excellence, aligning the executive officers’ long-term interests with those of the stockholders and motivating the executive officers to remain with the Company for long and productive careers.

Stockholders are urged to read the Compensation Discussion and Analysis beginning on page 31 of this proxy statement, as well as the Summary Compensation Table and related compensation tables and narrative, appearing on pages 43 through 59 which provide detailed information on the Company’s compensation policies and practices and the compensation of the Company’s named executive officers.

This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board. Although non-binding, the Board and the Compensation Committee will review and consider the voting results when evaluating the Company’s executive compensation program on an ongoing basis. At our 2023 Annual Meeting of Stockholders, our stockholders supported, on an advisory basis, the Board’s proposal that the say-on-pay advisory vote occur on an annual basis. The Board favors a policy of providing for annual say-on-pay advisory votes. It is anticipated the next say-on-pay advisory vote will occur at the Company’s 2027 Annual Meeting of Stockholders.

At the 2025 Annual Meeting of Stockholders, the Company’s stockholders overwhelmingly approved the “say-on-pay” proposal with more than 91% of the shares voted being cast in favor of the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE ADVISORY RESOLUTION TO APPROVE COMPENSATION OF NAMED EXECUTIVE OFFICERS.

TABLE OF CONTENTS

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The Company has adopted a written policy for the review and approval of transactions and arrangements between the Company and the Company’s current directors, director nominees, current executive officers, greater than five percent stockholders, and their immediate family members. All transactions, regardless of amount, are required to be reported to and reviewed by the General Counsel of the Company who is required to report the results of his review to the Board or independent Directors, as appropriate. Following this review, the Board would determine whether any such transaction is in, or not inconsistent with, the best interests of the Company and its stockholders, taking into consideration whether any such transaction is on terms no less favorable to the Company than those available with unrelated third parties and the related person’s interest in the transaction. As required under the rules of the SEC, transactions that are determined to be directly or indirectly material to the Company or a related person must be disclosed in the Company’s proxy statement.

Affiliates of FMR LLC (“Fidelity”) provide investment management services or other services in connection with the Company’s 401(k) plans and the DC SERP. In 2025, with respect to the 401(k) plans and DC SERP managed by Fidelity, (i) participants paid $2,659,295 (net) in mutual fund manager’s fees, and $949,545 in participant direct fees and (ii) the Company paid $42,019 in plan sponsor direct fees. In 2025, with respect to the pension plan and related SERP, the Company incurred $325,717 in asset management fees to Fidelity. The related investment management agreements were entered into on an arm’s-length basis.

No other related party transactions were identified during or subsequent to 2025 where the amount involved exceeded $120,000. As such, there are no other transactions to be reported in this proxy statement.

STOCK OWNERSHIP GUIDELINES FOR
NON-EMPLOYEE DIRECTORS AND CERTAIN EXECUTIVES

The Company has adopted stock ownership guidelines for its non-employee directors and certain of its executive officers. Each non-employee director is encouraged to own shares of the Company having a total value equal to at least 5x the annual cash retainer for Board service. The CEO is required to own shares of the Company having a total value equal to at least 6x base salary. The CFO is required to own shares of the Company having a total value equal to at least 3x base salary. Any new non-employee director or CEO or CFO will have five years from the date of his/her appointment to attain the required level of stock ownership. For purposes of this requirement, 60% of the value (assuming a cashless exercise) of vested but unexercised stock options count in determining stock ownership. Stock ownership does not include unvested stock options. There may be rare instances where the stock ownership guidelines would place a severe financial hardship on the director or executive. The Compensation Committee of the Board may, in its discretion, modify the stock ownership requirements in special circumstances.

CLAWBACK POLICY

The Company has adopted a Policy for Recovery of Erroneously Awarded Compensation (the “Clawback Policy”) in compliance with Exchange Act Rule 10D-1 and the corresponding NYSE Listing Standards. The Clawback Policy addresses the recovery of amounts from incentive-based awards in the event the Company must prepare an accounting restatement to correct the Company’s material noncompliance with any financial reporting requirement under securities laws, including restatements that correct an error in previously issued financial statements (a) that is material to the previously issued financial statements or (b) that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The Clawback Policy applies to current and former executive officers of the Company and reflects the Company’s culture that emphasizes accountability based on performance. A copy of our Clawback Policy is included as an exhibit to the Company’s 2025 Annual Report.

INSIDER TRADING COMPLIANCE POLICY

The Company has adopted an Insider Trading Compliance Policy that governs the purchase, sale and other dispositions of the Company’s securities by directors, officers, employees and other persons designated by the Company (including a household member of any of the foregoing persons) that the Company believes is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the NYSE Listing Standards. Our Insider Trading Compliance Policy, amongst other things, prohibits trading while in

TABLE OF CONTENTS

possession of material nonpublic information and includes pre-clearance procedures for certain specified employees who have regular access to material nonpublic information about the Company in the normal course of their duties. A copy of our Insider Trading Compliance Policy is included as an exhibit to the Company’s 2025 Annual Report.

POLICIES AND PRACTICES RELATED TO THE GRANT OF CERTAIN EQUITY AWARDS
CLOSE IN TIME TO THE RELEASE OF MATERIAL NONPUBLIC INFORMATION

The Committee maintains equity grant practices and procedures, including with respect to the timing of awards of stock options. Although the Committee does not have a formal policy with respect to the timing of stock options, the Committee has historically made annual awards of stock options in the second quarter of each year. Newly hired or promoted executive officers or key management employees have on occasion received an award of stock options at or near the date of hiring or promotion. The Committee does not grant stock options with an exercise price that is less than the closing price of the Common Stock on the grant date. The Committee’s general practice is to not grant stock options in anticipation of the release of material nonpublic information, or use such information in determining the terms of stock option awards. In addition, the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. During 2025, no stock options were granted to the NEOs during any period beginning four business days before the filing or furnishing of a periodic or current report with the SEC that disclosed material non-public information and ending one business day after the filing or furnishing of such reports.

PROHIBITION ON SHORT SALES, TRANSACTIONS IN
DERIVATIVE SECURITIES AND HEDGING

The Company has a written policy prohibiting officers and directors from engaging in (i) short sales of the Company’s securities, (ii) transactions in puts, calls or other derivative securities involving the Company’s securities, (iii) hedging transactions involving the Company’s securities, (iv) purchases of the Company’s securities on margin (other than a cashless exercise of stock options under the Company’s equity plans), and (v) any pledges of the Company’s securities to secure margin or other loans.

INVESTOR OUTREACH

Amphenol regularly engages with key stockholders to discuss, among other items, governance issues to ensure that management and the Board understand and address issues that are important to the Company’s stockholders. Through these engagements, the Company has obtained valuable feedback. For example, in 2023, the Company adopted the Clawback Policy in compliance with the applicable rules of the SEC and the NYSE Listing Standards. In addition, in 2022, the Company adopted an amendment to the Company’s By-Laws to provide that in contested elections, directors will be elected under a plurality voting standard. This varies from the Company’s majority voting standard in uncontested elections. In prior years, the Company has taken a variety of other significant actions in response to investor feedback, such as adopting an

TABLE OF CONTENTS

amendment to the By-Laws to implement “proxy access”, which, subject to the requirements of the By-Laws, permits stockholders to nominate candidates for election to the Board, lowering the threshold to call special meetings of stockholders from 50% to 25%, declassifying the Board and providing for the annual election of directors, allowing stockholders to act by written consent and eliminating supermajority voting requirements in the Company’s Certificate of Incorporation and By-Laws.

The Company’s Board welcomes direct engagement with significant stockholders to discuss matters of interest to such stockholders. Any such an engagement can be arranged by calling Lance D’Amico, our Executive Vice President, General Counsel and Secretary, at (203) 265-8606.

SUSTAINABILITY REPORT

At Amphenol, we believe that making sustainable business choices, building strong relationships with our stakeholders and engaging in good corporate governance create long-term value for our Company. Whether through minimizing 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. Throughout Amphenol, we have a shared commitment to create innovative products and enable technologies that improve the lives of people around the world, to support the well-being of our employees and communities and to sustain the health of our planet.
