## Corporate Governance
We describe key features of the Company's corporate governance environment below and in the next section of this proxy statement, captioned "Board of Directors and Committees." Our key corporate governance materials are available online at <u>corporate.marsh.com/about/corporate-governance.html</u>.

Overview

Our Board currently has thirteen (13) members, including H. Edward Hanway, our Independent Chair, and John Q. Doyle, our President and Chief Executive Officer. Mr. Doyle is the only member of management who serves as a director. As described in more detail under "Board of Directors and Committees," our Board maintains an Audit Committee, a Compensation Committee, a Directors and Governance Committee, a Finance Committee, a Business Responsibility Committee and an Executive Committee.

Corporate Governance Practices

The Company is committed to best practices in corporate governance. Highlights of our corporate governance practices are described below.

Board Structure

• **Board Independence.** All of the Company's directors are independent, with the exception of our CEO, who is the only member of management serving on the Board.

• **Independent Chair.** The Company maintains separate roles of chief executive officer and Board chair as a matter of policy. An independent director acts as Board chair.

Election of Directors

• **Annual Election of Directors.** The Company's charter provides for the annual election of directors.

• **Majority Voting in Director Elections.** The Company's bylaws provide that, in uncontested elections, director candidates must be elected by a majority of the votes cast. Each director candidate has previously tendered an irrevocable resignation that will be effective upon his or her failure to receive the requisite votes and the Board's acceptance of such resignation.

Proxy Access

• **Proxy Access.** The Company's bylaws permit a stockholder, or a group of up to 20 stockholders, owning 3% or more of the Company's outstanding common stock continuously for at least three years to nominate and include in the Company's proxy materials directors constituting up to the greater of two or 20% of board seats, if the stockholder(s) and the nominee(s) meet the requirements in our bylaws.

Right of Stockholders to Call Special Meetings

• **Stockholder Right to Call Special Meetings.** The Company's bylaws allow holders of record of at least 20% of the voting power of the Company's outstanding common stock to call a special meeting.

Stockholder Rights Plan

• **No Poison Pill.** The Company does not have a stockholder rights plan in place.

Compensation Practices

• **Compensation Structure for Independent Directors.** The Company's director compensation structure is transparent to investors and does not provide for meeting fees or retainers for non-chair committee membership.

• **Cap on Executive Severance Payments.** The Company is required as a matter of policy to obtain stockholder approval for severance agreements with certain senior executives if they provide for cash severance that exceeds 2.99x the executive's base salary and three-year average annual bonus award. Severance protections for our senior executives, including our CEO, are at a 1x multiple of base salary and bonus, as described in "Severance Arrangements" on page 51.

• **"Double-Trigger" Condition for Vesting of Equity-Based Awards following a Change in Control.** Our equity-based awards contain a "double-trigger" vesting provision, which requires both a change in control of the Company and a specified termination of employment in order for vesting to be accelerated.

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 1** 

------

#### **Table of Contents**

## Corporate Governance (Continued)
• **"Clawback" Policies.** We maintain a compensation clawback policy for senior executives that provides for the mandatory recoupment of erroneously awarded compensation in the event of a financial restatement in accordance with Securities and Exchange Commission rules and New York Stock Exchange listing standards. The Compensation Committee adopted an additional clawback policy for senior executives which provides for the recoupment of certain incentive compensation in the event of detrimental conduct by such senior executive. The Compensation Committee has the discretion to determine the manner and amount of incentive compensation to be clawed back pursuant to the policy.

Equity Ownership, Holding Requirements and Insider Trading

• **Senior Executive Equity Ownership and Holding Requirements.** The Company requires senior executives to hold shares or stock units of our common stock (excluding performance stock units) with a value equal to a multiple of base salary. The multiple for our Chief Executive Officer is six, and the multiple for our other senior executives is three. Senior executives are required to hold shares of the Company's common stock acquired in connection with equity-based awards until they reach their ownership multiple and may not sell any shares of the Company's common stock unless they maintain their ownership multiple (other than to meet tax withholding obligations or to pay the exercise price for options). Stock options (whether vested or unvested) are not counted in the ownership calculation. Additionally, outstanding performance stock units, which have a variable payout based on performance, are excluded from the calculation of ownership needed to satisfy the guidelines.

• **Director Equity Ownership and Holding Requirements.** Directors are required to acquire over time, and thereafter hold (directly or indirectly), shares or stock units of our common stock with a value equal to at least 5x the Board's basic annual retainer. Directors may not sell shares of the Company's common stock until this ownership threshold is attained.

• **Insider Trading Policies.** We have adopted insider trading policies and procedures governing the purchase, sale and/or other dispositions of securities of the Company by our directors, executive officers and employees, and have implemented processes for the Company that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as the NYSE listed company rules.

Guidelines for Corporate Governance

The Company and the Board formally express many of our governance policies through our Guidelines for Corporate Governance (our "Governance Guidelines"). The Governance Guidelines are posted on our website at <u>corporate.marsh.com/about/corporate-governance.html.</u>

The Governance Guidelines summarize certain policies and practices designed to assist the Board in fulfilling its fiduciary obligations to the Company's stockholders, including the following (parenthetical references are to the relevant section of the Governance Guidelines):

• The Board's responsibility, alongside management, for setting the "tone at the top" and overseeing management's strategy to promote a culture of integrity throughout the Company. (Section A)

• Specific Board functions (Section B), such as:

Corporate Focus

• overseeing the integrity of the Company's financial statements and financial reporting processes;

• reviewing processes to maintain the Company's compliance with legal and ethical standards; and

Stockholder Engagement Program

Our stockholder engagement program is a comprehensive, year-round process that incorporates an analysis of our annual meeting results and focuses on key topics of importance to our shareholders. The program is designed to build and maintain strong relationships so we can better understand investor perspectives and priorities. We engage with shareholders on a variety of topics, including our executive compensation and corporate governance programs, as well as business responsibility and sustainability. At Marsh, the stockholder engagement program complements the work performed by our Investor Relations team in regularly communicating with our shareholders, including through investor conferences and meetings. The program is designed to encompass a dialogue with our shareholders on several levels, including (i) periodic virtual or telephonic meetings with our larger institutional shareholders, involving, as appropriate, direct engagement with members of the Board; (ii) responses to shareholder questions; (iii) discussions with proponents of stockholder proposals; and (iv) engagement with proxy advisory firms.

Feedback received during the engagement process helps shape our practices and is shared with senior executives, the Board and its committees, including the Directors and Governance Committee. We are committed to ongoing engagement with our shareholders, and we intend to continue these outreach efforts.

## Corporate Governance (Continued)
Risk Oversight

It is the responsibility of the Company's senior management to assess and manage our exposure to risk and to review with the Board the most material risks facing the Company. Our annual enterprise risk management review process consists of a bottom-up review of all material risks facing Marsh, with business risk committees ultimately escalating risks to the Marsh Risk Committee and a top-down review of all material risks facing the company through Board and Executive Committee risk assessments. The Board oversees risk management directly and through its committees. The Board believes its approach to risk oversight allows it to appropriately allocate oversight responsibilities among and between the full Board and its committees.

Annually, the Board reviews management's assessment of the Company's key enterprise risks. Senior management then briefs the Board on its strategy with respect to each risk and provides a mid-year status update and a report at year-end. The Board also receives updates from management on specific risks throughout the year, including geopolitical and macroeconomic, cybersecurity, regulatory and human capital management.

The Audit Committee regularly reviews the Company's policies and practices with respect to risk assessment and risk management, including cybersecurity risk and artificial intelligence. The Directors and Governance Committee considers risks related to CEO succession planning, the Compensation Committee considers risks relating to the design of executive compensation programs and arrangements and the Business Responsibility Committee considers risks related to business responsibility initiatives, including the evolving regulatory environment for sustainability matters and our policies and practices regarding political contributions. See the discussion under "Committees" on page 14 for additional information about the Board's committees.

Business Responsibility Oversight and Activities

The Company has a Management Business Responsibility Committee that supports the Marsh Board and senior executives in identifying, aligning and prioritizing new and existing business responsibility objectives across Marsh. Our 2025 Business Responsibility Report is available on our website at <u>corporate.marsh</u><u>.com</u><u>/about/business-responsibility.html</u> and discloses against aspects of the International Sustainability Standards Board (ISSB) International Financial Reporting Standards (IFRS), which incorporate the recommendations of the TCFD Task Force on Climate-related Financial Disclosures (TCFD), Sustainability Accounting Standards Board (SASB) and Global Reporting Initiative (GRI) standards. Our Business Responsibility Report and our website are not deemed part of this proxy statement and are not incorporated by reference.

The Board oversees the Company's business responsibility initiatives and strategies primarily through its committees.

**Business Responsibility Committee.** The Business Responsibility Committee oversees the Company's (1) approach to environmental stewardship and sustainability, (2) strategies to foster a vibrant and inclusive culture and (3) responsible business practices, including government relations and public affairs initiatives. It is comprised of members who have been selected based upon their tenure, skills and expertise. The Business Responsibility Committee receives reports at least annually on environmental stewardship and sustainability matters from the Chair of the Company's Management Business Responsibility Committee and the Senior Director of Sustainability, on topics impacting our company culture from the Company's Chief People Officer, and on governmental relations and public affairs initiatives including our policies around political contributions from the Chief Public Affairs Officer. The Business Responsibility Committee coordinates with the Directors and Governance Committee and the Compensation Committee on areas of oversight covered by both committees.

**Compensation Committee.** The Compensation Committee has responsibility to review certain key human resource strategic activities, including those relating to talent management, succession planning, training and recruitment. The Compensation Committee receives annual reports on relevant topics from the Company's Chief People Officer.

**Directors and Governance Committee.** The Directors and Governance Committee takes a leadership role in shaping the Company's corporate governance principles and practices. It receives regular updates on governance practices and developments from the Company's General Counsel.

**Audit Committee.** The Audit Committee has responsibility for the Company's policies, systems and controls designed to promote ethical behavior and compliance with applicable legal and regulatory requirements. It receives regular updates from the Company's Chief Compliance Officer, Head of Internal Audit and Global Controller.

## Corporate Governance (Continued)
Following each committee meeting, the respective committee chair reports on the meeting to the full Board. See the discussion under "Committees" on page 14 for additional information about the Board's committees.

**Management Business Responsibility Committee.** An internal committee with members drawn from across the Company's senior management helps coordinate the Company's business responsibility. Members are drawn from senior management across our four global businesses and corporate departments, with our Deputy General Counsel, Chief Compliance Officer and Corporate Secretary serving as Chair.

Codes of Conduct

Our reputation is fundamental to our business. The Company's directors, senior executives and colleagues are expected to act ethically at all times. The Company's codes of conduct and ethics are posted on the Company's website at <u>corporate.</u><u>marsh</u><u>.com</u>.

The Greater Good

Our Code of Conduct, *The Greater Good*, is the cornerstone of our culture of integrity. Available in 13 languages, it underpins our values, ethical commitments and standards of business integrity and professionalism. It provides guidance on many topics including anti-corruption, data handling, conflicts of interest, trade sanctions and anti-money laundering and is aligned around three key pillars: (1) Win With Integrity, (2) You Are Never Alone, and (3) Speak Up.

*The Greater Good* applies to all of our directors, officers and other colleagues and requires the Company's agents, subcontractors and suppliers to comply with relevant aspects of our compliance policies. Each year, the Company's directors and senior executives certify their commitment to *The Greater Good*.

*The Greater Good* supports colleagues in making decisions in situations where it may not be clear — or easy. Our colleagues are provided with comprehensive training and communication of *The Greater Good*, including through our digital integrity hub. We have also deployed a one-click desktop shortcut on every company computer and mobile device to allow colleagues to seamlessly engage with our Code of Conduct.

Code of Ethics for the CEO and Senior Financial Officers

The Company has also adopted an additional Code of Ethics for the Chief Executive Officer and Senior Financial Officers, which applies to our chief executive officer, chief financial officer and controller. We will disclose any amendments to, or waivers of, the Code of Ethics for the Chief Executive Officer and Senior Financial Officers on our website at <u>corporate.marsh.com</u> within four business days.

CEO Succession Planning and Succession Planning for Senior Executives

The Board believes that planning for CEO succession is one of its most important responsibilities. CEO succession planning is regularly discussed at Board meetings and in executive sessions. In addition, every year our CEO and Chief People Officer review with the Board potential internal candidates, including their qualifications, experience and development. At least annually, independent directors meet with the CEO to discuss potential successor candidates and their qualifications, experience and preparedness. The Board, taking into account the recommendations of the Directors and Governance Committee, approves and maintains a succession plan for the CEO. A confidential procedure is also maintained for the timely and efficient transfer of the CEO's responsibilities in the event of an emergency or his sudden incapacitation or departure.

The Board also believes that planning for succession below the CEO level is a key responsibility. The CEO periodically reviews with the independent directors the performance of senior executives and their qualifications, experience and development. The Compensation Committee has responsibility for reviewing the Company's executive talent review process for senior executives. Every year, our Chief People Officer and CEO review with the Compensation Committee and full Board succession plans for direct reports to the CEO and other key executive positions.

## Corporate Governance (Continued)
Directors engage with senior executives and others at Board, committee and preparatory meetings. Directors also interact with senior executives and others in less formal settings to allow directors to personally assess potential candidates for CEO and senior executive roles.

Director Recruitment, Nomination and Succession Planning

The Board, taking into account the recommendation of the Directors and Governance Committee, is responsible for nominating a slate of director candidates for election at the Company's annual meeting of stockholders.

Director Recruitment

The Board has delegated to the Directors and Governance Committee the authority to identify, consider and recommend to the Board potential new director candidates. An overview of the Board's director recruitment process is provided below.

Director Nomination Planning

As part of the process for nominating director candidates, the Board evaluates each individual director in the context of the Board as a whole, with the objective of recommending a group that can best support the success of our business and represent stockholder interests. In deciding whether to nominate an incumbent director for re-election, the Board considers many factors, including the criteria described under "Director Qualifications" on page 10, as well as his or her length of service and performance on the Board.

## Corporate Governance (Continued)
Director Succession Planning

The Board is committed to effective succession planning. The Directors and Governance Committee has responsibility to review the composition and structure of the Board as a whole, taking into account such factors as the Board's current mix and diversity of skills, backgrounds and experiences, and to make recommendations to the Board as appropriate. In its review of Board composition, the Directors and Governance Committee considers succession planning in light of factors such as skills needed and upcoming retirements and other potential departures.

Changes in Directors Since the Last Annual Meeting of Stockholders

Bruce Broussard and Peter Harrison joined the Board in July 2025 and February 2026, respectively. They were identified and recommended to the Directors and Governance Committee by a search firm retained by the Committee. In addition to identifying and providing information on a number of potential director candidates during the process, the search firm reviewed and provided information about Mr. Broussard and Mr. Harrison for review by the Committee and the Board.

Director Orientation and Continuing Education

New directors participate in an orientation program throughout their first year on the Board to familiarize them with the Company's business, strategy, finances, policies, corporate governance practices and culture. The orientation program includes one-on-one meetings with the Company's senior executives and comprehensive background materials including our code of conduct, *The Greater Good.* Directors certify their commitment to *The Greater Good* when they join the Board and every year thereafter. Orientation sessions with key advisors are provided for incoming Audit and Compensation Committee members. Orientation sessions are also tailored upon request to meet directors' needs and interests.

Directors are also encouraged to participate in continuing education programs. Continuing education programs may be part of regular Board or committee meetings or third-party presentations. Additionally, the Company provides directors with access to third-party resources that provide updates on issues and programs relevant to public companies and their directors.

Director Independence

The Board has determined that all directors other than Mr. Doyle are independent under the New York Stock Exchange ("NYSE") listed company rules and the standards set forth in the Governance Guidelines. Therefore, the Board has satisfied the objective, set forth in the Governance Guidelines, that a substantial majority of the Company's directors be independent of management.

For a director to be considered independent, the Board must affirmatively determine that the director has no direct or indirect material relationship with the Company. The Board has established standards to assist it in making determinations of director independence. These standards conform to, or are more exacting than, the independence requirements provided in the NYSE listed company rules. The Company's director independence standards are set forth as Annex A to our Governance Guidelines.

All members of the Audit, Compensation and Directors and Governance Committees must be independent directors under the NYSE listed company rules and the standards set forth in the Company's Governance Guidelines. Members of the Audit Committee must also satisfy a separate Securities and Exchange Commission ("SEC") and NYSE independence requirement, which provides that they may not be affiliates and may not accept directly or indirectly any consulting, advisory or other compensatory fee from the Company or any of its subsidiaries, other than compensation received in their capacity as members of the Board or any committee of the Board. The Board evaluated each member of the Audit Committee and determined that they meet the separate SEC and NYSE independence requirement. The Board also evaluated each member of the Compensation Committee under the additional NYSE compensation committee member independence standards and determined that these members qualify as "non-employee directors" (as defined under Rule 16b-3 under the Securities Exchange Act of 1934).

Under our Governance Guidelines, if a director whom the Board has deemed independent has a change in circumstances or relationships that might cause the Board to reconsider that determination, the director must immediately notify the Independent Chair and the chair of the Directors and Governance Committee.

## Corporate Governance (Continued)
Review of Related Person Transactions

The Company maintains a written Policy Regarding Related Person Transactions, which sets forth standards and procedures for the review and approval of transactions between the Company and related persons. The policy is administered by the Directors and Governance Committee with assistance from the Company's Corporate Secretary.

In determining whether to approve a related person transaction, the Directors and Governance Committee will review the facts and circumstances including: the commercial reasonableness of the transaction; the benefits of the transaction to the Company; the availability of other sources for the products or services involved in the transaction; the materiality and nature of the related person's direct or indirect interest in the transaction; the potential public perception of the transaction and the potential impact of the transaction on the independence of any of the Company's directors. The Directors and Governance Committee will approve a related person transaction only if the Committee determines that the related person transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders.

Stockholder Recommendations and Nominations for Director Candidates

Stockholders may recommend or nominate director candidates in writing to the Company's Corporate Secretary. All stockholder recommendations for director candidates are considered, and they are evaluated in the same manner as other director candidates. Recommendations should be delivered to the Company's Corporate Secretary at our principal executive offices: Marsh, Attn: Directors and Governance Committee, c/o Corporate Secretary, 1166 Avenue of the Americas, New York, New York 10036-2774.

Stockholder nominations for director elections must meet the requirements described in Article III of our bylaws. The notice of nomination also must meet bylaw requirements, including as the procedures and information required. See the discussion under "Submission of Stockholder Proposals and Other Items of Business for 2027 Annual Meeting" on page 87.

Director Election Voting Standard

The Company's bylaws provide that, in an uncontested election of directors, such as this one, where the number of nominees does not exceed the number of directors to be elected, a director nominee must receive more votes cast "for" than "against" his or her election in order to be elected to the Board.

In connection with the Company's majority voting standard for director elections, the Board has adopted the following procedures, which are set forth more fully in Section E.3 of our Governance Guidelines:

• The Board shall nominate for election only director candidates who agree to tender to the Board an irrevocable resignation that will be effective upon (i) a director's failure to receive the required number of votes for re-election at the next meeting of stockholders at which he or she faces re-election and (ii) the Board's acceptance of such resignation.

• Following a meeting of stockholders at which an incumbent director who was a nominee for re-election does not receive the required number of votes for election, the Directors and Governance Committee shall make a recommendation to the Board as to whether to accept or reject such director's resignation. Within 90 days following the certification of the election results, the Board, taking into account the recommendation of the Directors and Governance Committee and any other factors and information it deems relevant, shall decide whether to accept or reject the director's resignation and shall publicly disclose that decision and its rationale.

• If the Board accepts a director's resignation, the Directors and Governance Committee will recommend to the Board whether to fill the resulting vacant Board seat or reduce the size of the Board.

## Board of Directors and Committees
Board Composition, Leadership and Size

At the 2026 annual meeting, stockholders will vote on the election of thirteen (13) directors. H. Edward Hanway currently serves as the Board's Independent Chair.

The only member of management who serves on the Board is John Q. Doyle, the Company's President and Chief Executive Officer. The position of Chair of the Board has been held by an independent director since 2005. The Board believes that this currently is the best leadership structure for the Company.

![LOGO](g94896g01a27.jpg)

Director Qualifications

As provided in our Governance Guidelines, all directors must demonstrate the highest standards of ethics and integrity, must be independent thinkers with strong analytical ability and must be committed to representing all of the Company's stockholders rather than any particular interest group. In addition to these characteristics, our Governance Guidelines provide that each director candidate be evaluated by the Board against the following criteria: (1) the candidate's personal and professional reputation and background; (2) the candidate's knowledge and experience with the company's businesses and industries; (3) the candidate's experience with businesses or other organizations comparable to the Company in terms of size or complexity; (4) the interplay of the candidate's skills and experience with those of the incumbent directors; (5) the extent to which the candidate would provide substantive expertise that is currently sought by the Board or any committees of the Board; (6) the candidate's ability to commit the time necessary to fulfill a director's responsibilities; (7) relevant legal and regulatory requirements and evolving best practices in corporate governance; (8) the personal and professional experiences of each candidate and (9) any other criteria the Board deems appropriate.

## Board of Directors and Committees (Continued)
Board Refreshment

The Board is committed to effective succession planning and refreshment. Seven independent directors have joined in the last seven years, enhancing the Board's breadth and depth of experience. The average tenure of our directors standing for election is eight years. In deciding whether to nominate an incumbent director for re-election, the Board considers many factors, including tenure and an assessment of independence. The Board believes that term limits may arbitrarily deprive the Board of the contributions of directors who have valuable insight, developed over time, into the Company and its industries. The Board believes that a mix of director tenures provides fresh viewpoints, institutional knowledge and historical perspective.

Retirement

Our Governance Guidelines require our independent directors not to stand for re-election at the annual meeting of stockholders following their 75th birthday. Any director who is an employee of the Company will resign from the Board when his or her employment ends.

Attendance

The Board held seven meetings during 2025. The average attendance by directors at meetings of the Board and its committees held during 2025 was approximately 97%. All directors attended at least 75% of the meetings of the Board and committees on which they served. The Board's policy is to have all directors attend the annual meetings of stockholders. All directors who were then directors, attended the 2025 annual meeting of stockholders.

Executive Sessions

Our independent directors meet in executive session without management at regularly scheduled multi-day Board meetings. In 2025 they held six executive sessions, which were presided over by the Independent Chair. In addition, the members of the Audit, Compensation and Directors and Governance Committees meet in executive session without management at regularly scheduled committee meetings.

Board and Committee Evaluations

Our Governance Guidelines provide that the Directors and Governance Committee oversees an annual evaluation of the Board's performance and effectiveness. In addition, the charters for the Audit, Compensation, Directors and Governance, Finance and Business Responsibility Committees provide that each committee evaluates its own performance annually.

Board Evaluations

The annual evaluation of the Board focuses on its contribution to the Company over the preceding year, including areas in which the Board or management believes the Board could enhance its future contributions. More generally, directors are encouraged to make suggestions at any time for improving the Board's practices.

An overview of the Board self-evaluation process is provided below.

For the evaluation of 2025, the Directors and Governance Committee considered the form of the evaluation and determined to use a questionnaire soliciting qualitative commentary and quantitative ratings from each director and to conduct individual director interviews every other year as part of the self-evaluation process.

The questionnaire begins with open-ended discussion questions and also solicits the directors' views on topics such as:

Committee Evaluations

The Audit, Compensation, Directors and Governance, Finance and Business Responsibility Committees evaluate their own performance annually pursuant to their respective charters. Material is provided in advance to assist the committee with assessing its performance of its responsibilities under its charter and our Governance Guidelines. These materials include questions for discussion, summaries of the committee's activities and responsibilities and feedback from the Board self-evaluation regarding the committee. Committee self-evaluations are conducted in executive session.

Committees

Our Board maintains an Audit Committee, a Compensation Committee, a Directors and Governance Committee, a Finance Committee, a Business Responsibility Committee and an Executive Committee to assist the Board in discharging its responsibilities. Following each committee meeting, the respective committee chair reports the highlights of the meeting to the full Board.

Membership on each of the Audit, Compensation and Directors and Governance Committees is limited to independent directors as required by the Company, the NYSE listed company rules and the SEC's independence rules. The Business Responsibility and Finance Committees must consist of a majority of independent directors as required by the Company. Each of these committees is governed by a charter, which is available on our website at <u>corporate.marsh.com/about/corporate-governance.html</u>.

Audit Committee

The Audit Committee is charged, among other things, with assisting the Board in fulfilling its oversight responsibilities with respect to:

• our financial reporting processes and practices, and the integrity of the Company's financial statements, including reviewing the adequacy and effectiveness of the Company's internal controls over financial reporting in compliance with Section 404 of the Sarbanes-Oxley Act of 2002;

• the qualifications, independence and performance of our independent registered public accounting firm;

• the performance of the Company's internal audit function, including reviewing issues identified in internal audits and management's response, and discussing the annual internal audit plan and staffing;

• the Company's policies and implementation of systems and controls designed to promote ethical behavior;

• compliance by the Company with legal and regulatory requirements;

• the Company's enterprise risk management programs and processes, including cyber risk management and risks related to artificial intelligence, information security, technology and controls; and

• the approval of the Audit Committee Report for our proxy statement.

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

## Board of Directors and Committees (Continued)
The Audit Committee selects, oversees and approves, pursuant to a pre-approval policy, all services to be performed by our independent registered public accounting firm. Additionally, the Audit Committee assesses the scope, staffing, and fees for the annual audit and other audit services provided by our independent registered public accounting firm, as well as whether to appoint a new firm. The Company's independent registered public accounting firm reports to the Audit Committee.

**Meeting Schedule.** The Audit Committee met eleven times in 2025, including dedicated meetings to review quarterly earnings releases and financial filings with the SEC. The committee engages in regular communications with management to discuss material risk oversight matters. In addition, the Audit Committee regularly meets in separate executive sessions at which only Audit Committee members are present and in separate private sessions with each of management, internal auditors, and our independent registered public accounting firm.

**Required Qualifications.** The Board has determined that each of the Audit Committee members is independent within the meaning of applicable laws and listing standards. Additionally, all members of the Audit Committee are "financially literate," as required by the NYSE and determined by the Board. The Board has determined that Anthony K. Anderson, Bruce Broussard, Judith Hartmann and Jan Siegmund have the requisite qualifications to satisfy the SEC definition of "audit committee financial expert."

Compensation Committee

The primary responsibilities of the Compensation Committee are to:

• evaluate the performance and determine the compensation of our chief executive officer;

• review and approve the compensation of our other senior executives;

• review from time to time the Company's compensation strategy in light of the Company's business objectives;

• review certain key human resource strategic activities, including those relating to talent management, succession planning, training and recruitment; and

• oversee and discharge its responsibilities for the Company's incentive compensation plans for our senior executives and equity-based award plans, including the Company's clawback policies.

**Meeting Schedule.** The Compensation Committee met five times in 2025, including a special meeting in February to complete its annual review of, and make decisions on, executive compensation. Decisions relating to significant matters are usually presented to the Compensation Committee and discussed at more than one meeting to allow for full consideration of the implications and possible alternatives before a final decision is made. The Compensation Committee receives support from its independent compensation consultant and the Company's management, including the Company's human resources staff, as described below. At each of its meetings, the Compensation Committee meets in executive session and without management present. The independent compensation consultant attends portions of the executive sessions.

The Compensation Committee may delegate all or a portion of its duties and responsibilities to the chair of the Compensation Committee or a subcommittee of the Compensation Committee. If necessary, the chair is authorized to take action on behalf of the Compensation Committee between its regularly scheduled meetings, within prescribed guidelines. If any such action is taken, the chair reports such action to the Compensation Committee at its next regularly scheduled meeting.

The Compensation Committee reports its discussions on a regular basis and, where appropriate, reviews its actions, including executive compensation determinations, with the full Board.

**Independent Compensation Consultant.** The Compensation Committee has engaged Pay Governance LLC as its independent compensation consultant to support the Compensation Committee in performing its duties and to provide analysis and make recommendations to the Compensation Committee regarding our executive compensation program. The independent compensation consultant reports directly to the Compensation Committee and provides advice and analysis solely to the Compensation Committee. The independent compensation consultant supports the Compensation Committee by:

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 15**

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

## Board of Directors and Committees (Continued)
• participating in meetings and executive sessions of the Compensation Committee to advise the Compensation Committee on specific matters that arise;

• offering objective advice regarding the compensation and policy recommendations presented to the Compensation Committee by the Company's management, including human resources colleagues; and

• providing data regarding the compensation practices of comparable companies.

The Compensation Committee requested and received advice from the independent compensation consultant with respect to all significant matters addressed by the Compensation Committee during 2025. Except for the services provided to the Board, neither the individual compensation consultant nor Pay Governance LLC nor any of its affiliates provided any services to the Company or its affiliates in 2025.

The Compensation Committee assessed the work of Pay Governance LLC during 2025 pursuant to SEC rules and the listing standards of the NYSE and concluded that Pay Governance LLC's work did not raise any conflict of interest.

**Company Management.** The Company's management, including senior human resources colleagues, supports the Compensation Committee by:

• developing meeting agendas in consultation with the chair of the Compensation Committee and preparing background materials for Compensation Committee meetings;

• making recommendations to the Compensation Committee on the Company's compensation philosophy, governance initiatives and short-term and long-term incentive ("LTI") compensation design, and by providing input regarding the individual performance component of annual bonus awards; and

• responding to actions and initiatives proposed by the Compensation Committee.

In addition, our President and Chief Executive Officer provides recommendations with respect to the compensation of our other senior executives.

Our President and Chief Executive Officer, senior members of the Company's human resources staff and internal legal counsel attended Compensation Committee meetings when invited but were not present for executive sessions or for any discussion of their own compensation.

**Timing and Procedures of Equity-Based Compensation Awards.** Annual equity-based awards under our LTI compensation program are approved at a prescheduled meeting of the Compensation Committee each February and, consistent with our historical practice, are granted on that same date. The timing of grants was determined by the Compensation Committee to be appropriate to incentivize senior executives to deliver on the Company's strategic objectives for the fiscal year and coincides with our calendar-year compensation and performance review cycle, thereby strengthening the link between pay and performance.

In addition, the Compensation Committee periodically grants restricted stock unit ("RSU") awards to newly hired senior executives and to continuing senior executives for increased responsibilities that accompany changes in position and for retention purposes. These awards are approved at prescheduled meetings of the Compensation Committee. The Compensation Committee has also authorized our President and Chief Executive Officer to make such awards to individuals who are not senior executives, subject to prescribed parameters. These awards are granted on the first calendar day of the month following approval of the award by the Compensation Committee or our President and Chief Executive Officer, as applicable. In the event that an award is approved prior to an individual's employment start date with the Company, the award will be granted on the first calendar day of the first month on or following the individual's employment start date; however, if an award is approved contingent on the award recipient providing documentation supporting the forfeiture of compensation from a former employer and that documentation has not been provided as of the individual's employment start date, the award will be granted on the first calendar day of the month following the provision of such documentation and acceptance by the Company.

Typically, equity-based awards are denominated as a dollar value and then converted into a number of PSUs, RSUs or stock options. The number of PSUs or RSUs is determined based on the fair market value of the Company's common stock. The number of stock options is determined based on the grant date fair value of a stock option to purchase a share of the Company's common stock. The grant date fair value of stock options, PSUs or RSUs is determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, *Compensation-Stock Compensation* ("FASB ASC Topic 718"). We believe that our equity-based compensation grant procedures effectively protect against the manipulation of grant timing for employee gain.

**16 \| Marsh & McLennan Companies, Inc. \|** *Notice of Annual Meeting and 2026 Proxy Statement* 

------

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

Under the 2020 Incentive Stock and Stock Award Plan, the fair market value of the Company's common stock is defined as the average of the high and low trading prices of the Company's common stock on the trading day immediately preceding the grant date. Under the Amended and Restated 2020 Incentive and Stock Award Plan, the fair market value of the Company's common stock is defined as the closing price of the Company's common stock on the trading day immediately preceding the grant date.

The Company does not grant stock options or PSUs to our executive officers in anticipation of the release of significant earnings announcements or other material non-public information ("MNPI") likely to result in changes to the price of our common shares. Similarly, we do not time the release of MNPI based on equity award grant dates. In the event MNPI becomes known to the Compensation Committee prior to granting an equity award, the Compensation Committee will take the existence of such information into consideration and use its business judgment to determine whether to delay the grant of equity to avoid any appearance of impropriety.

The Company's human resources staff regularly monitors, and updates the Compensation Committee on, the use of shares of the Company's common stock for equity-based awards and the number of shares available for future awards under our equity-based compensation plans. As part of the process of granting annual LTI compensation, the Compensation Committee considers share use and equity run rate (a measure of the potential dilutive impact of the Company's equity award program, defined as the number of shares underlying awards granted plus the number of shares underlying awards assumed upon acquisition (if any), divided by weighted average common shares outstanding) so that annual LTI awards, and the extent to which shares of the Company's common stock are used for those awards, are maintained at a reasonable level.

Directors and Governance Committee

The Directors and Governance Committee's duties and responsibilities include, among other things:

• assisting the Board by identifying, considering and recommending, consistent with criteria approved by the Board, qualified candidates for election as directors, including the slate of directors to be nominated by the Board for election at the Company's annual meeting of stockholders;

• recommending Board committee assignments;

• overseeing the development and implementation of succession planning for the Company's chief executive officer; and

• taking a leadership role in shaping the Company's corporate governance, including developing and recommending to the Board the Company's Guidelines for Corporate Governance.

Finance Committee

The Finance Committee reviews and makes recommendations to the Board concerning, among other matters, the Company's capital structure, capital management and methods of corporate finance (including proposed issuances of securities or other financing transactions) and proposed acquisitions, divestitures or other strategic transactions.

Business Responsibility Committee

The Business Responsibility Committee's purpose is to oversee the Company's (1) approach to environmental stewardship and sustainability, (2) strategies to foster a vibrant and inclusive culture and (3) responsible business practices, including government relations and public affairs initiatives. The Business Responsibility Committee receives at least annual updates on business responsibility and reports to the Board on a regular basis. The Business Responsibility Committee also receives a comprehensive report and briefing on Government Relations activities, including lobbying and advocacy, at least annually.

Executive Committee

The Executive Committee is empowered to act for the full Board during the intervals between Board meetings, except with respect to matters that, under Delaware law or the Company's bylaws, may not be delegated to a committee of the Board. The Executive Committee meets as necessary, with all actions taken by the Committee reported at the next Board meeting.

## Election of Directors

## Item 1:

## Election of Directors
At the 2026 annual meeting, stockholders will vote on the election of the thirteen (13) nominees listed on the following page for a one-year term. As described under "Director Recruitment, Nomination and Succession Planning" on page 6, Mr. Broussard and Mr. Harrison joined the Board in July 2025 and February 2026, respectively, and they will appear on the ballot for the first time.

The Board has nominated each of these individuals to serve until the 2027 annual meeting. Each nominee has indicated that he or she will serve if elected. We do not anticipate that any of the nominees will be unable or unwilling to stand for election, but if that happens, your proxy may be voted for another person nominated by the Board or the Board may reduce its size. Each director holds office until his or her successor has been duly elected and qualified or his or her earlier resignation, death or removal.

In nominating the following slate of director candidates for election at the Company's annual meeting of stockholders, the Board has evaluated each nominee by reference to the criteria described above on pages 10 and 11 under the headings "Director Qualifications" and "Director Skills and Experience." In addition, the Board evaluates each individual director in the context of the Board as a whole, with the objective of recommending a group that can best support the success of our businesses and represent stockholder interests.

The following section contains information provided by the nominees about their principal occupations, business experience and other matters, including their current committee assignments, as well as a description of how each individual's experience qualifies him or her to serve as a director of the Company.

2025 and 2026 Annual Total Direct Compensation of Named Executive Officers

The following table summarizes the decisions made by the Compensation Committee in February 2026 and February 2025 with respect to the annual total direct compensation of our named executive officers. Because this table shows compensation by decision date rather than by fiscal year, it includes our 2026 annual LTI awards, which are not shown in the "2025 Summary Compensation Table" on page 57. The compensation decisions reflected here, and the rationale for such decisions, are discussed in "Executive Compensation Determinations" beginning on page 37.

(1) Annual LTI awards as determined by the Compensation Committee are denominated in U.S. dollars and granted as a combination of stock options and PSUs. For stock options, 50% of the LTI value shown in the table is converted into a number of stock options based on the grant date fair value per share using the Black-Scholes option pricing model. For PSUs, 50% of the LTI value shown in the table is converted into a number of PSUs based on the fair market value of Company common stock. For annual LTI awards granted in 2025, the fair market value of the Company's common stock is defined as the average of the high and low trading prices of the Company's common stock on the trading day immediately preceding the grant date. For annual LTI awards granted in 2026, the fair market value of the Company's common stock is defined as the closing price of the Company's common stock on the trading day immediately preceding the grant date. The grant date fair value of the PSUs, as calculated in accordance with FASB ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative TSR modifier, which is a market condition. In addition, stock options and PSUs granted are rounded up to the nearest whole number.

Elements of Compensation

The principal elements of our executive compensation program are base salary, annual bonuses and annual LTI awards. The Compensation Committee believes that each compensation element, and all of these elements combined, are important to maintain an executive compensation program that is competitive, performance-based and stockholder-focused.

Our integrated compensation framework heavily weights variable compensation to reward achievements against pre-established, quantifiable financial performance objectives and individual strategic performance objectives. In addition, because a significant portion of variable compensation is delivered in the form of equity-based awards, the value ultimately realized by our senior executives from these awards depends on stockholder value creation as measured by the future performance of our stock price and also our TSR versus S&P 500 constituents, which operates as a modifier for payouts of our PSU awards.

## Executive Compensation (Continued)
Executive Compensation Determinations

The Compensation Committee takes a total compensation approach in setting the pay of our senior executives and makes decisions regarding base salary, annual bonuses and annual LTI awards in February of each year. This approach enables the Compensation Committee to evaluate performance on a consistent basis each year and to consider the appropriate level of fixed and variable compensation within each senior executive's total compensation package.

While the Compensation Committee recognizes that elements of compensation may be interrelated, it does not require or assume any fixed relationship among the various elements of compensation within the total direct compensation framework or between the compensation of our CEO and that of any other senior executive. In addition, accrued pension and amounts realized or realizable under previously granted equity-based awards did not influence the Compensation Committee's decisions.

The Compensation Committee considers the recommendations of our CEO when determining the compensation of our other senior executives. No named executive officer participates in portions of any meetings during which decisions are made regarding his or her own compensation. The final salary adjustments and incentive awards to named executive officers are approved solely by the Compensation Committee.

Base Salary

Base salary is the only component in our executive compensation program that is not variable "at-risk" pay. In setting base salaries, the Compensation Committee reviews the senior executive's skills and experience, the competitive market for his or her position and internal equity considerations.

Effective April 1, 2025, the Compensation Committee increased the base salary of Mr. Klisura from $800,000 to $900,000. The Compensation Committee determined that this increase was appropriate based on a review of the competitive market and an evaluation of Mr. Klisura's performance as President and Chief Executive Officer of Guy Carpenter.

When setting compensation at its February 2026 meeting, the Compensation Committee chose not to adjust any of the NEOs' base salaries.

The 2025 and 2026 base salaries of our named executive officers are shown in the "2025 and 2026 Annual Total Direct Compensation of Named Executive Officers" table on page 32.

Annual Bonus

The Compensation Committee determined the 2025 annual bonus awards for our named executive officers using the following framework:

![LOGO](g94896g01a61.jpg)

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 37**

## Executive Compensation (Continued)
The Compensation Committee established the annual bonus framework and rigorous financial performance targets for the performance metrics in early 2025.

In 2025, the Compensation Committee made the following increases to target annual bonuses:

• Mr. McGivney from $1,750,000 to $1,900,000;

• Mr. South from $2,300,000 to $2,450,000;

• Mr. Tomlinson from $1,900,000 to $2,100,000; and

• Mr. Klisura from $1,900,000 to $2,100,000.

The Compensation Committee determined that these increases in target annual bonus opportunity were appropriate based on a review of the competitive market and their performance. The Committee believes that, in our industry, competition for talent is significant and targets must be set competitively to attract, retain and reward executive talent. Mr. Doyle's target annual bonus opportunity was not increased in 2025.

In determining 2025 annual bonus awards, each senior executive's target annual bonus was allocated between financial and strategic performance according to weightings associated with his or her position. The Compensation Committee then assessed financial performance and each senior executive's strategic performance and determined a payout level for each portion of the senior executive's target annual bonus.

The multiplier for Company financial performance as reflected by adjusted EPS growth (as modified for executive compensation purposes) versus target was determined and applied to the sum of the payout levels for financial and strategic performance for each senior executive.

Using this result, the Compensation Committee then conducted a qualitative assessment to determine the actual bonus award for each senior executive. The Compensation Committee believes that the use of judgment in the qualitative assessment helps reward performance appropriately, particularly on a year-to-year basis.

Actual bonus payments are capped at 200% of target, which the Compensation Committee believes limits the incentive for excessive risk-taking.

Financial and Strategic Performance Measures

The Compensation Committee selected the following measures and weightings for the 2025 annual bonus awards:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | Financial Performance | Financial Performance | Strategic Performance | Strategic Performance |
| &nbsp;&nbsp;&nbsp;&nbsp; Senior Executive | Weighting | Measure | Weighting | Measure |
| &nbsp;&nbsp;&nbsp; Company CEO | 80% | Company<br>net operating income | 20% | Individual objectives established for each senior executive |
| &nbsp;&nbsp;&nbsp; Other Corporate | 80% | Company<br>net operating income | 20% | Individual objectives established for each senior executive |
| &nbsp;&nbsp;&nbsp; Senior Executives | 70% | Company<br>net operating income | 30% | Individual objectives established for each senior executive |
| &nbsp;&nbsp;&nbsp; Business Chief Executive Officers | 80% | Business<br>net operating income | 20% | Individual objectives established for each senior executive |

---

The financial performance measure used for Company and business net operating income in the 2025 annual bonus framework is defined in "Definitions of Financial Performance Measures" on page 48.

## Executive Compensation (Continued)
The financial performance factor for net operating income ranged from 0% to a maximum of 150% of the target level as indicated in the following table:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Performance Level | Performance<br>as a % of Target | Financial<br>Performance Factor |
| &nbsp;&nbsp;&nbsp; Maximum | ≥110% | 150% |
| &nbsp;&nbsp;&nbsp; Target | 100% | 100% |
| &nbsp;&nbsp;&nbsp; Threshold | 90% | 50% |
| &nbsp;&nbsp;&nbsp; Below Threshold | <90% | <50% |

---

Note: Interpolation is used to determine the performance factor for performance as a percentage of target between threshold/target or target/maximum. In the event of performance below threshold, the Compensation Committee would exercise its discretion to determine a financial performance factor ranging from 0% up to 50%.

2025 Financial Performance

For 2025, the financial performance measure for all senior executives was Company or business net operating income, as applicable, as modified for executive compensation purposes. The Compensation Committee set challenging targets for our named executive officers to align with our 2025 objective of driving strong income growth across the Company.

Performance targets for 2025 were set above our actual performance for 2024. Performance targets were based on threshold, target and maximum levels in dollars rather than growth rates. Target and actual results in the table below are expressed as a percentage of prior-year results.

2025 Strategic Performance

In early 2025, the Compensation Committee reviewed strategic objectives, relating to operational performance, growth initiatives, risk management and human capital established by each named executive officer. The bonus framework has a 0% to 150% payout scale for strategic performance.

At the beginning of 2026, the Compensation Committee reviewed the strategic accomplishments for each named executive officer for 2025. The Compensation Committee and Mr. Doyle (and, in the case of Mr. Doyle, solely the Compensation Committee) assessed each named executive officer's strategic performance as above target for the year and determined a performance factor ranging up to a maximum of 150% for 2025 strategic performance.

2025 Multiplier for Company Financial Performance

The financial performance factor for the Company is measured by annual adjusted EPS growth, resulting in a 0.70x to 1.30x multiplier as indicated in the following table. For 2025, the target for adjusted EPS growth was 8%.

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Performance Level | Adjusted EPS Growth versus Target | Multiplier | Multiplier |
| &nbsp;&nbsp;&nbsp; Maximum | Target plus 2 percentage points (or higher) |  | 1.30x |
| &nbsp;&nbsp;&nbsp; Target | Target |  | 1.00x |
| &nbsp;&nbsp;&nbsp; Minimum | Target minus 2 percentage points (or lower) |  | 0.70x |

---

Note: Interpolation is used to determine the multiplier for a percentile ranking between minimum/target or target/maximum.

The financial performance measure used for adjusted EPS growth in the 2025 annual bonus framework is defined in "Definitions of Financial Performance Measures" on page 48.

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

## Executive Compensation (Continued)
Using the framework described above, our annual adjusted EPS growth as modified for executive compensation purposes relating to the 2025 bonus framework was 8.8% (versus the 10% maximum), resulting in a multiplier of 1.12x.

2025 Qualitative Assessment

The Compensation Committee believes that the use of qualitative judgment in making final bonus award decisions helps evaluate performance appropriately on a year-to-year basis and also on an internal equity basis among our senior executives. In addition to performance as measured against the previously described financial and strategic objectives, the Compensation Committee assessed the manner in which these objectives were achieved. For each senior executive, the Compensation Committee also considered his or her current-year performance and bonus award vis-à-vis his or her prior-year performance and bonus award, compensation relative to peers at direct competitors and his or her total direct compensation. The Compensation Committee reviewed the Company's financial performance as a whole, including our relative financial performance. The Compensation Committee recognized that underlying growth tempered in 2025, due to complex market conditions. However, the Company had a solid performance year, driven by increases in EPS, revenue and operating income. We also achieved our 18th consecutive year of reported adjusted margin expansion. As a result, the Compensation Committee determined that bonuses for our named executive officers would be above target for 2025, but down as compared to the prior-year bonus awards. This assessment reflects the Compensation Committee's holistic view of individual and Company performance and ensuring that our compensation program aligns with the interests of our stockholders.

Determination of 2025 Annual Bonuses

Using its assessment of the 2025 financial and strategic performance factors and the Company's financial performance factor as its basis, the Compensation Committee determined the 2025 bonus award for each named executive officer in the manner described above. The actual annual bonuses paid to our named executive officers for 2025 were as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Name | 2025 Target<br>Bonus Award | 2025 Bonus<br>as a % of Target | 2024 Actual<br>Bonus Award | 2025 Actual<br>Bonus Award | % Change |

| &nbsp;&nbsp;&nbsp; Mr. McGivney | $1900000 | 163% | $3300000 | $3100000 | -6% |
| &nbsp;&nbsp;&nbsp; Mr. South | $2450000 | 143% | $4250000 | $3500000 | -18% |
| &nbsp;&nbsp;&nbsp; Mr. Tomlinson | $2100000 | 129% | $3100000 | $2700000 | -13% |
| &nbsp;&nbsp;&nbsp; Mr. Klisura | $2100000 | 157% | $3800000 | $3300000 | -13% |

Annual LTI Awards

In 2025, the Compensation Committee increased Mr. Doyle's target LTI award from $13,750,000 to $16,750,000 based on a review of peer data and his performance as President and Chief Executive Officer. The Compensation Committee also increased the target LTI awards of our other NEOs as follows:

• Mr. McGivney from $3,450,000 to $3,600,000,

• Mr. South from $2,800,000 to $3,200,000, and

• Mr. Klisura from $1,800,000 to $2,000,000.

The Compensation Committee believes these increases were appropriate based on a review of the competitive market, their past performance and expected future contributions to our long-term performance. The competition for talented executives in our industry remains intense. Further, our success has made our senior executives more appealing as candidates for employment with other companies, and we believe that these market conditions, together with their strong performance, require our targets to be set competitively.

The Compensation Committee set Mr. Tomlinson's target LTI award at $2,300,000 in connection with his promotion to President and Chief Executive Officer of Mercer in April 2024.

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 43**

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

## Executive Compensation (Continued)
The Compensation Committee determined the 2026 annual LTI awards granted to our named executive officers as described in more detail in "Determination of 2026 Annual LTI Awards" on page 44, would comprise stock options and PSUs, as summarized in the following table:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Award Type | Performance Alignment |
| &nbsp;&nbsp;&nbsp; Stock Options (50%) | Rewards stock price appreciation and the creation of stockholder value |
| &nbsp;&nbsp;&nbsp; Performance Stock Units (50%) | Rewards the achievement of specific Company financial objectives and relative TSR versus S&P 500 constituents |

---

The Compensation Committee selected S&P 500 constituents as the comparator group for the relative TSR modifier given that a broad index is commonly used by other companies that have relative TSR as a performance measure. In addition, we compete for "investment dollars" against other S&P 500 constituents rather than narrowly against our peer group for executive compensation, which is relatively small and subject to potentially significant change over time.

Determination of 2026 Annual LTI Awards

The annual equity-based awards granted to our senior executives are determined by the Compensation Committee as part of its annual total compensation review. In determining the awards, the Compensation Committee considers the senior executive's performance and his or her expected future contributions to the Company's performance along with external market competitiveness, internal equity comparisons and the target LTI award set forth in the senior executive's employment letter. The CEO also provides LTI award recommendations for senior executives other than himself.

The annual LTI awards granted to our named executive officers in February 2026 are shown in the following table. They are not reflected in the "2025 Summary Compensation Table" on page 57 because the awards were made after the end of the 2025 fiscal year.

(1) Annual LTI awards as determined by the Compensation Committee are denominated in U.S. dollars and granted as a combination of stock options and PSUs. For stock options, the value shown in the table was converted into a number of stock options based on the grant date fair value per share using the Black-Scholes option pricing model. For PSUs, the value shown in the table was converted into a number of PSUs based on the fair market value of Company common stock, which was equal to closing price of shares of the Company common stock on the trading date immediately preceding the date of grant. The grant date fair value of the PSUs, as calculated in accordance with FASB ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative TSR modifier, which is a market condition. In addition, stock options and PSUs granted are rounded up to the nearest whole number.

The value ultimately realized from these awards depends on the future performance of our stock price and, for PSU awards, achieving specific Company financial objectives and the Company's relative TSR versus S&P 500 constituents. Vesting is contingent on the named executive officer's continued service, except in certain circumstances such as retirement. The terms and conditions of these awards are described in the narrative following the "2025 Grants of Plan-Based Awards Table" on page 60.

## Executive Compensation (Continued)
PSU Awards

The performance measure for PSU awards, which represent 50% of the 2026 annual LTI compensation for our senior executives, is adjusted EPS growth as modified for executive compensation purposes and measured on a three-year annualized growth rate basis. The PSUs granted also include a modifier based on the Company's three-year TSR versus S&P 500 constituents. Depending on our actual financial performance results, along with relative TSR performance, 0% to 200% of the number of PSUs granted is delivered in shares of our common stock. Our PSU awards are calibrated to reward our senior executives for solid performance while the 200% payout cap limits the incentive for excessive risk-taking. We believe that granting PSU awards annually, with each award focused on future performance, encourages our senior executives to focus on long-term stockholder value.

The following tables provide the payout (as a percentage of target) for maximum, target and threshold performance levels for the 2023 through 2026 awards. The Compensation Committee sets the performance levels after reviewing our financial strategy, the design of PSU awards at peer group companies, forward-looking strategic goals and historical EPS growth data for S&P 500 constituents. At the time of setting the target and determining the payouts at varying levels of performance for these awards, the Compensation Committee believed that achievement of the target for annualized adjusted EPS growth was a challenging goal.

The payout of the PSU awards is determined as follows:

![LOGO](g94896g01a67.jpg)

The financial performance measures used in the PSU awards granted in 2023 to 2026 are defined in "Definitions of Financial Performance Measures" on page 48.

Performance and Payout Levels for Our 2023 to 2026 PSU Awards

The adjusted EPS growth measure for our PSU awards is shown in the following table. The three-year target for annualized adjusted EPS growth is 8% for our PSU awards granted in 2023 to 2026. As noted previously, the Compensation Committee aims to set rigorous performance levels, taking into account our financial strategy, the design of PSU awards at peer group companies (including growth targets) and historical EPS growth data for S&P 500 constituents.

Note: Interpolation is used to determine the relative TSR modifier (as a percentage of target) for a performance result between minimum/target or target/maximum.

Performance Results for Our 2023 PSU Awards

The following charts show three-year results for the 2023 PSU awards granted to our senior executives. Our 12.7% annualized adjusted EPS growth was above maximum and qualified for a 200% EPS performance factor. However, our 38<sup>th</sup> percentile relative TSR versus S&P 500 constituents was below target and corresponded to a .88x relative TSR modifier. As a result, the PSU payout for the 2023 PSU award was 176% of target, as discussed in the next section.

The Compensation Committee believes the financial performance targets for the 2023 PSU awards were rigorous. The achievement of a 200% EPS performance factor and 0.88x relative TSR Modifier represent significant Company achievement over the performance period, as well as our pay for performance program through which the financial interest of our senior executives is aligned with the return of our stockholders.

Summary of PSU Awards Granted from 2023 through 2025

The table below summarizes the three-year performance periods for PSU awards granted from 2023 to 2025, including the payout at 176% of target for our 2023 PSU award based on 12.7% annualized adjusted EPS growth as modified for executive compensation purposes. The 12.7% annualized adjusted EPS growth represents a period of strong and sustained financial performance by the Company. As discussed previously, the PSU awards granted also include a modifier based on the Company's three-year TSR versus S&P 500 constituents. For the 2023 PSU award, our three-year TSR was at the 38th percentile versus S&P 500 constituents, which resulted in a 0.88x relative TSR modifier.

The adjusted EPS growth and relative TSR measures used in the PSU awards are defined in "Definitions of Financial Performance Measures" on page 48.

![LOGO](g94896g03a68.jpg)

The actual payout for 2024 and 2025 PSU awards will depend on three-year performance, except under certain circumstances that may require earlier measurement of results, such as the death of a participant or a change in control of the Company.

Peer Group Companies and Surveys

Peer Group for Executive Compensation Purposes

In 2025, the Compensation Committee reviewed the executive compensation data disclosed in the publicly available filings of the companies that comprise our peer group for executive compensation purposes. The peer group is based on business lines, talent pool and company size, as reflected by revenue and market capitalization, and includes insurance, consulting and other business services companies, as listed in the table below. The Compensation Committee reviews the peer group periodically and makes adjustments that it deems are appropriate or necessary, for example, as a result of business combinations and other changes. The Compensation Committee has not made any changes to the peer group since September 2019.

Financial Services and General Industry Surveys

The Compensation Committee also reviews executive compensation data drawn from two industry subsets (Financial Services and General Industry) of S&P 500 constituents that participated in an executive compensation survey conducted by an independent compensation consulting firm. Each subset was refined based on revenue and market capitalization. For a list of the companies comprising these subsets, please refer to Exhibit B. The business CEO comparisons were based on subsidiaries or divisions of all companies that participated in the executive compensation survey (instead of only S&P 500 constituents) in order to have a significant sample size for these particular comparisons.

## Executive Compensation (Continued)
Benefit Plans and Other Programs

Retirement and Deferred Compensation Plans

We offer retirement and deferred compensation plans, in which all of our senior executives are eligible to participate to maintain a competitive compensation program.

We maintain a defined contribution retirement program in the U.S. consisting of the Supplemental Savings & Investment Plan ("SSIP"), an unfunded nonqualified defined contribution retirement plan that is coordinated with our 401(k) Savings & Investment Plan ("401(k) Plan"), a tax-qualified contribution plan. Additional information about the SSIP, including individual amounts deferred by our named executive officers, Company matching credits and earnings during 2025, as well as account balances as of the end of 2025, is presented in the "2025 Nonqualified Deferred Compensation Table" on page 65. Earnings with respect to all of our nonqualified deferred compensation plans are based upon actual market performance, and preferential or above-market earnings are not offered.

We discontinued future service accruals in our U.S. defined benefit retirement programs effective December 31, 2016. The features of our U.S. retirement programs, including the present value of the accumulated pension benefits for our named executive officers as of the end of 2025, are presented in further detail in "Defined Benefit Retirement Program" on page 64. We do not have individually-designed defined benefit arrangements for any named executive officer.

Severance Arrangements

Severance payments and benefits for our senior executives are provided under our Senior Executive Severance Pay Plan, which provides for severance payments in the event of an involuntary termination of employment without "cause" (as defined in the plan) in an amount equal to the sum of the senior executive's then-current base salary and average annual bonus award over the three prior years, plus an amount equal to a pro-rata bonus for the year of termination calculated based on the senior executive's target annual bonus for the calendar year in which the termination date occurs multiplied by a fraction, the numerator of which is the number of days that have elapsed in such calendar year through the termination date and the denominator of which is 365.

While compensation decisions regarding our senior executives affect the potential payments under these arrangements, the existence of these severance arrangements did not influence the Compensation Committee's decisions with respect to other elements of compensation for our named executive officers because these severance arrangements are contingent in nature and may never be triggered.

The terms of the Senior Executive Severance Pay Plan are discussed more fully in "Termination of Employment" on page 69. The amount of the estimated payments and benefits payable to our named executive officers, assuming a termination of employment as of the last business day of 2025, is presented in "Potential Payments Upon Termination or Change in Control" beginning on page 66.

Change-in-Control Arrangements

Change-in-control payments and benefits are provided to our senior executives through our equity-based compensation plans and the Senior Executive Severance Pay Plan, as applicable. These arrangements are intended to retain our senior executives and provide continuity of management in the event of an actual or potential change in control of the Company. Consistent with this objective, the terms of our equity-based awards contain a "double-trigger" vesting provision, which requires both a change in control of the Company and a subsequent specified termination of employment for vesting to be accelerated. The Senior Executive Severance Pay Plan also includes a "double-trigger" change-in-control provision rather than providing severance payments and benefits solely on the basis of a change in control of the Company. We believe that requiring a "double trigger," rather than providing severance payments (and accelerated vesting of equity-based awards) solely on the basis of a change in control, is more consistent with the purpose of encouraging the continued employment of our senior executives following a change in control of the Company.

We do not provide any excise tax payments, reimbursements or "gross ups" in connection with a change in control of the Company to any of our senior executives under any plan or arrangement.

The amount of the estimated payments and benefits payable to our named executive officers, assuming a change in control of the Company and subsequent specified termination of employment as of the last business day of 2025, is presented in "Potential Payments Upon Termination or Change in Control" beginning on page 66.

Other Benefits and Perquisites

Our senior executives are eligible to participate in our health and welfare benefit programs on the same basis as our other eligible employees. We also provide certain perquisites and other personal benefits to our senior executives. In general, the perquisites or other personal benefits provided to our senior executives include (i) the cost of financial counseling and certain income tax return preparation, (ii) from time to time, relocation or housing costs associated with hiring a newly recruited or promoted senior executive, and (iii) effective in 2025, an annual voluntary executive physical program. The incremental cost of providing perquisites and other personal benefits during 2025 to our named executive officers is presented in the footnotes to the "All Other Compensation" column of the "2025 Summary Compensation Table" on page 57.

In addition to the above, in 2023 we commissioned a security study to analyze security risks to our President and Chief Executive Officer and developed a security policy. In accordance with the security policy, we continue to provide access to a Company car and a driver with security training credentials commensurate to what is recommended in the study to Mr. Doyle.

Beginning in 2024, in an effort to make more efficient use of Company resources, a pool of cars was made available to Mr. Doyle in accordance with the security study, and to other senior executives for business use only. The Company believes the carpool increases both efficiency and provides the necessary security for Mr. Doyle and our other senior executives to travel safely and conduct business efficiently while in transit. The incremental cost to Mr. Doyle for his personal use is detailed in the footnotes to the "All Other Compensation" column of the "2025 Summary Compensation Table" on page 57.

In 2025, in light of executive security concerns, the Compensation Committee reassessed its security protocols for senior executives. This process included commissioning a new security study to analyze the potential risks to our Chief Financial Officer and the Chief Executive Officers of our four businesses. Based on the findings of this study, effective January 1, 2025, the Compensation Committee determined it was prudent to expand the use of the carpool for purposes of commuting to and from work to these senior executives . We have included such costs in the amounts reported in the "All Other Compensation" column of the "2025 Summary Compensation Table" on page 57.

Additionally, in connection with the Company's commitment to safeguarding its leadership team, the Compensation Committee approved covering the costs to procure, install and maintain residential security measures for all senior executives when deemed necessary for their safety. Because certain components of the residential security measures may be viewed as conveying a personal benefit to a named executive officer, we include the costs in the "All Other Compensation" column of the "2025 Summary Compensation Table" on page 57.

We believe the scope and costs of these measures serve important business purposes and constitute reasonable, necessary and appropriate expenses for the benefit of the Company and its stockholders. Since the costs arise from the nature of our senior executives' roles and employment responsibilities at the Company, we do not consider them to be personal benefits. However, in accordance with SEC rules, we have reported the incremental costs of such personal security measures for our Chief Executive Officer and our other named executive officers in the "All Other Compensation" column in the "2025 Summary Compensation Table".

The Compensation Committee has also determined to provide to the President and Chief Executive Officer of the Company access to corporate aircraft, in which we maintain fractional interests, for business and personal travel. Such personal air travel is limited to an amount not to exceed $275,000 per calendar year as determined based on the aggregate incremental cost of such travel to the Company.

The imputed income attributable to the President and CEO's personal use of corporate aircraft and the senior executives' personal use of the car and driver (including commuting) is taxable income to such individuals. The taxes associated with this income are not reimbursed or paid by the Company.

## Executive Compensation (Continued)
Risk and Reward Features of Executive Compensation Program

The Compensation Committee strives to maintain an appropriate balance between risk and reward in support of our overall business strategy. Our executive compensation principles, policies and practices are designed to encourage an appropriate level of risk-taking, but not to encourage our senior executives to take excessive or unnecessary risks. To achieve this balance, we maintain the following policies and practices:

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Feature | Description |
| Balanced Total Compensation Approach | The mix of base salary, annual bonus awards and annual LTI awards appropriately balances the shorter-term and longer-term aspects of each senior executive's responsibilities and performance, without undue emphasis on any single element of compensation. |
| Performance-Based Annual Bonus Program | Awards to senior executives are made based on both financial performance measures, relating to fiscal year performance, and strategic performance objectives, which may relate to longer-term and qualitative objectives. Each senior executive's target annual bonus and payout range of 0% to 200% is set forth in his or her employment letter. The Compensation Committee determines the bonus for each of our senior executives. We do not guarantee annual bonuses for our senior executives, except in special situations such as the initial bonus award after a senior executive's hire if the guarantee is deemed necessary to attract a candidate to join the Company. |
| Stockholder-Focused LTI Program | Equity-based awards for our senior executives are granted annually on a discretionary basis by the Compensation Committee taking into consideration each individual's past performance and expected future contributions. Awards made in 2025 were in a combination of stock options and PSU awards to align the financial interests of our senior executives with maximizing our return to stockholders. PSU awards are earned based on our achievement against financial performance objectives and the Company's TSR versus S&P 500 constituents over a three-year performance period, both as determined by the Compensation Committee. The payout of PSU awards is capped at 200% of PSUs granted. |
|  | All equity-based awards are subject to multi-year vesting requirements or performance periods with complete forfeiture of unvested awards upon a voluntary termination of employment by a senior executive (other than by reason of retirement) or termination of employment for cause. None of our equity-based awards are scheduled to begin vesting until at least one year following their grant. In addition, the terms of our outstanding and unvested equity-based awards contain a "double-trigger" vesting provision in the event of a change in control of the Company. We do not provide any excise tax payments, reimbursements or "gross ups" in connection with a change in control of the Company to any of our senior executives under any plan or arrangement. |
| Executive Stock Ownership Guidelines | Our senior executives are required to acquire and hold shares or stock units (excluding PSUs) of our common stock with an aggregate value at least equal to a specified multiple of their base salary. Stock options (whether vested or unvested) are not counted in the ownership calculation. Our senior executives may not sell shares acquired in connection with the distribution of stock units or exercise of stock options until and unless the specified multiple of base salary is reached and maintained (other than to meet tax withholding obligations or to pay the exercise price of stock options). |
|  | Our guidelines exclude the counting of outstanding PSUs, which have a variable payout based on performance, in the calculation of ownership needed to satisfy the guidelines. |

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Feature | Description |
| Prohibition Against Speculative Activities, Hedging or Pledging of Company Stock | We prohibit our employees, including our senior executives and directors, from engaging in speculative or hedging activities (including short sales, purchases or sales of puts or calls and trading on a short-term basis) in our common stock. We prohibit our senior executives and directors from pledging our securities as collateral for a loan or for any other purpose. We also prohibit our senior executives and directors from holding our securities in a margin account. |
| Compensation Recovery Policies | In accordance with the requirements set forth in the New York Stock Exchange (NYSE) Clawback listing standard (and the SEC final Clawback Rule), the Company adopted the Marsh & McLennan Companies, Inc. Compensation Clawback Policy (the "Recoupment Policy"), which provides for the recoupment of erroneously awarded incentive compensation in the event that (i) such incentive compensation awarded to a current or former executive officer was calculated based on financial results that were required to be restated due to material noncompliance with financial reporting requirements and (ii) the noncompliance resulted in overpayment of incentive compensation paid or granted within the three-year period preceding the date the restatement was required. In addition, our 2011 and 2020 Incentive and Stock Award Plans give us the ability to provide for a clawback of outstanding or already-settled equity-based awards. The Recoupment Policy is disclosed as an exhibit to the Company's Annual Report on Form 10-K. |
|  | The Compensation Committee also approved a clawback policy that provides for the recoupment of certain incentive compensation in the event that the Compensation Committee determines that a senior executive engaged in specified detrimental conduct (the "Clawback Policy"). The Compensation Committee has the discretion to determine the manner and amount of incentive compensation to be clawed back pursuant to the Clawback Policy. |
| 10b5-1 Trading Arrangements | We have adopted insider trading policies and procedures governing the purchase, sale and/or other dispositions of securities of the Company by our directors, executive officers and employees, and have implemented processes for the Company, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as the NYSE Corporate Governance Standards. In addition, our senior executives must receive approval through pre-clearance procedures in order to transact in securities of the Company. Our Trading Securities Policy are described under Item 10 to our annual report on 10-K for the year ended December 31, 2025. |
| Severance Payments | Severance protections for our senior executives are set at a uniform level equal to his or her base salary and three-year average annual bonus award (a "1x multiple"). In addition, without stockholder approval, we will not enter into a severance agreement with a senior executive that provides for any cash severance payment that exceeds 2.99x the sum of his or her base salary and three-year average annual bonus award. |

---

In light of the above and based on management's annual review and analysis focused on the incentive compensation programs covering our general employee population, we believe our compensation policies and practices do not encourage excessive or inappropriate risk-taking and that the risks arising from our compensation policies and practices for our employees are not reasonably likely to have a material adverse effect on the Company.

## Executive Compensation (Continued)
Stock Ownership Guidelines

We maintain stock ownership guidelines for our senior executives that are intended to align the financial interests of our senior executives with our stockholders by requiring them to acquire and maintain a meaningful ownership interest in our common stock. These guidelines are intended to take into account an individual's needs for portfolio diversification, while maintaining an ownership interest at levels sufficient to assure our stockholders of management's commitment to long-term value creation. Our senior executives are required, over a five-year period, to acquire and hold shares or stock units (excluding PSUs) of our common stock with an aggregate value at least equal to a specified multiple of their base salary. Stock options (whether vested or unvested) are not counted in the ownership calculation. In January 2022, the Compensation Committee amended the guidelines to exclude PSUs from the ownership calculation and, in view of the significant impact of the change, adopted a transition guideline providing all of our senior executives five years to reach the required multiple of base salary.

The current multiples for all senior executives are as follows:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Named Executive Officer | Ownership Level<br>(as a multiple of base salary) | Ownership Level<br>(as a multiple of base salary) |
| &nbsp;&nbsp;&nbsp; CEO |  | 6x |
| &nbsp;&nbsp;&nbsp; Other named executive officers |  | 3x |

---

As of February 28, 2026, all of our named executive officers (except for Mr. Tomlinson) had an ownership interest that was above the required multiple of base salary. Mr. Tomlinson has until April 1, 2029 to acquire and hold shares or stock units (excluding PSUs) of our common stock to reach the minimum.

Additional information concerning our stock ownership guidelines is available on our website under: <u>corporate.marsh.com/about/corporate-governance.html</u>.

Holding Requirement for Equity-Based Awards

Under our stock ownership guidelines, our senior executives are required to hold all shares of our common stock acquired in connection with the distribution of stock units or exercise of stock options (net of any tax withholding and, in the case of stock options, the exercise price) until the required multiple of base salary is reached. In addition, unless approved by the CEO, our senior executives

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 55** 

------

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

## Executive Compensation (Continued)
(other than the CEO) may not sell any shares of our common stock, however acquired, unless their ownership interest after such sale is at or above the required multiple of base salary stipulated under our stock ownership guidelines. The CEO is similarly permitted if approved by the Chair of the Compensation Committee. Mr. Doyle has not requested such approval during his tenure as CEO.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code generally disallows public companies a federal income tax deduction for compensation in excess of $1 million that is paid to certain former or current senior executives in any taxable year. The Compensation Committee reserves the right to award compensation that is not tax deductible.

We also structure compensation in a manner intended to avoid the incurrence of any additional tax, interest or penalties under Section 409A of the Internal Revenue Code governing the provision of nonqualified deferred compensation to our service providers.

We account for stock-based compensation in accordance with FASB ASC Topic 718, which requires us to recognize compensation expense relating to share-based payments (such as stock options, PSU awards and RSU awards) in our financial statements. The recognition of this expense has not caused us to limit or otherwise significantly alter the equity-based compensation element of our executive compensation program. This is because we believe equity-based compensation is a necessary component of a competitive executive compensation program and fulfills important program objectives. The Compensation Committee considers the potential impact of FASB ASC Topic 718 on any proposed change to the equity-based compensation element of our program.

Additional Considerations

This Compensation Discussion and Analysis includes statements regarding the use of various performance measures and related target levels in the limited context of our executive compensation program. These target levels are not intended to be statements of management's expectations of our future financial results or other guidance. Investors should not apply these target levels in any other context.

Compensation Committee Report

The Compensation Committee has reviewed and discussed with management the preceding Compensation Discussion and Analysis, as well as the accompanying compensation tables and related narratives. Based on that review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated into the Company's Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 9, 2026.

(1) Mr. Tomlinson was appointed President and Chief Executive Officer, Mercer and Vice Chair, Marsh on April 1, 2024. Mr. Tomlinson's compensation is shown for 2024 and 2025 since he was not a named executive officer in 2023.

(2) The amounts reported in the "Stock Awards" and "Option Awards" columns represent the aggregate grant date fair value of the awards for the years ended December 31, 2025, December 31, 2024 and December 31, 2023, respectively, computed in accordance with FASB ASC Topic 718 and using Black-Scholes (excluding the effect of estimated forfeitures). The amounts reported in the "Stock Awards" column represent PSU awards for 2025, 2024 and 2023. The grant date fair value reported for the 2025 PSU awards is based on performance at the target level and, as calculated in accordance with FASB ASC Topic 718, is determined using a Monte Carlo simulation model since payouts are based in part on a relative total stockholder return ("TSR") modifier, which is a market condition. As stated in the description of the PSU awards following the "2025 Grants of Plan-Based Awards Table" on page 60, the payout based on maximum performance is 200% of the target level, which, if achieved, would correspond to the values reported in the table below, holding constant the grant date fair value of the Company's common stock. The assumptions used in calculating the amounts reported for awards granted in 2025 are included in footnote 9 to the Company's audited financial statements for the fiscal year ended December 31, 2025, included in the Company's Annual Report on Form 10-K filed with the SEC on February 9, 2026. The assumptions used in calculating the amounts reported for awards granted prior to 2025 are included in footnote 9 captioned "Stock Benefit Plans" to the Company's audited financial statements for the relevant fiscal year, included in the Company's Annual Reports on Form 10-K previously filed with the SEC. The amounts reported in these columns may differ slightly from the corresponding amounts shown in the "2025 Grants of Plan-Based Awards Table" on page 60 due to rounding to the nearest whole dollar as required by SEC rules. In addition, the amounts reported in these columns may differ slightly from the amounts disclosed in the "2025 and 2026 Annual Total Direct Compensation of Named Executive Officers" section on page 32 of the Compensation Discussion and Analysis due to rounding to the nearest whole share.

(3) The amounts reported in the "Non-Equity Incentive Plan Compensation" column represent the amounts received for annual bonus awards, as described in the "Annual Bonus" section beginning on page 37 of the Compensation Discussion and Analysis. The awards earned in respect of 2025 were determined by the Compensation Committee at its meeting on February 24, 2026 and were paid on February 27, 2026.

(4) The amounts reported in the "Change in Pension Value and Nonqualified Deferred Compensation Earnings" column represent the increase, if any, in the present value of the named executive officers' benefits (both vested and unvested) under the tax-qualified Marsh & McLennan Companies Retirement Plan, the Company's Benefit Equalization Plan and the Company's Supplemental Retirement Plan. For 2025, the amount reported for each named executive officer reflects changes in age and service, the interest rate and the mortality assumption projecting longer life expectancies, and any change in base salary. The assumptions used in calculating the amounts reported are included in footnote 8 to the Company's audited financial statements for the fiscal year ended December 31, 2025, included in the Company's Annual Report on Form 10-K filed with the SEC on February 9, 2026. The Company's retirement programs are described in further detail in "Defined Benefit Retirement Program" on page 64. No named executive officer received preferential or above-market earnings on deferred compensation. The Company discontinued future service accruals in the United States Defined Benefit Retirement Program effective December 31, 2016.

(a) These amounts include the Company's matching contributions under the 401(k) Plan and SSIP attributable to 2025. The 401(k) Plan is a tax-qualified defined contribution plan. The SSIP is a nonqualified defined contribution plan and is described in further detail in the "2025 Nonqualified Deferred Compensation Table" section on page 65.

(b) This amount represents interest credited on the named executive officer's account within the Company's tax-qualified employee stock purchase plan.

(c) These amounts represent the cost to the Company of offering personal financial planning and tax preparation services to the named executive officers. The imputed income attributable to these services was taxable income to the named executive officer. The taxes associated with this income were not reimbursed or paid by the Company.

## Executive Compensation (Continued)
(d) This amount represents the incremental cost to the Company of Mr. Doyle's personal use of corporate aircraft, in which the Company owns fractional interests, in accordance with his employment letter. The incremental cost has been calculated by adding the incremental variable costs associated with personal flights (including hourly charges, taxes, passenger fees, international fees, ground services and catering). The imputed income attributable to his personal use of corporate aircraft was taxable income to Mr. Doyle. The taxes associated with this income were not reimbursed or paid by the Company. The limit on the amount of personal air travel for the President and CEO is $275,000.

(e) We maintain a pool of cars and drivers to all of our senior executives for business use, and to Mr. Doyle for personal use. Effective January 1, 2025, in light of additional security concerns, our NEOs may also use the carpool for purposes of commuting to and from work. The amounts reported in this column represent the approximate cost to the Company of the senior executives' personal use of the carpool (including commuting), in accordance with the recommendations of our security study. The imputed income attributable to this use was taxable income to the senior executives. The taxes associated with this income were not reimbursed or paid by the Company.

(f) This amount represents the cost to the Company of security for Mr. Doyle, and as of January 1, 2025, our other NEOs, in connection with their role. This includes overtime costs allocable to Company-provided security and security personnel to safeguard the our NEOs. This amount also represents the residential security costs paid by the Company for the applicable NEOs. We believe the scope and costs of these measures serve important business purposes and constitute reasonable, necessary and appropriate expenses for the benefit of the Company and its stockholders. Since the costs arise from the nature of our President and Chief Executive Officer's and other named executive officers' roles and their employment responsibilities at the Company, we do not consider them to be personal benefits to our CEO or our other named executive officers. However, in accordance with SEC rules, we have reported them here.

(g) This amount represents the cost to the Company for a voluntary executive physical examination.

(6) The total amounts reported in this column may not equal the sum of amounts reflected in the preceding columns due to rounding to the nearest whole dollar as required by SEC rules.

Employment Letters

During 2025, Mr. Doyle's terms of employment as our President and Chief Executive Officer, as approved by the Compensation Committee, were as follows:

• an annual base salary of $1,500,000;

• an annual bonus with a target level of $3,750,000;

• an annual long-term incentive ("LTI") award with a target grant date fair value of $16,750,000;

• continued participation in the Senior Executive Severance Pay Plan; and

• access to a car and driver for business and personal use, including work/home travel, and to corporate aircraft in which we maintain fractional interests, for business and personal travel (with such personal air travel limited to an amount not to exceed $275,000 per calendar year as determined based on the aggregate incremental cost of such travel to the Company).

In consideration for his employment arrangements, Mr. Doyle entered into confidentiality, noncompetition and nonsolicitation covenants in favor of the Company for the duration of his employment and for 24 months following his termination of employment.

The Company also has employment letters with each of the other named executive officers that follow a common template, approved by the Compensation Committee, and include the following principal terms:

• Base salary, target annual bonus and target annual LTI award, and applicable payment ranges. Actual annual bonus payments and annual LTI awards are based on factors described in the "Annual Bonus" section on page 37 and "Annual LTI Awards" section on page 43 of the Compensation Discussion and Analysis;

• Participation in the Company's Senior Executive Severance Pay Plan, as described in the "Severance Arrangements" section on page 51 of the Compensation Discussion and Analysis and the "Potential Payments Upon Termination or Change in Control" section on page 66;

• Access to a car and driver for business and work/home travel; and

• Confidentiality, noncompetition, and nonsolicitation covenants in favor of the Company.

(1) The equity-based awards granted on February 18, 2025 reported in this table were approved by the Compensation Committee at its meeting on the same date.

(2) The actual annual cash bonuses awarded to the named executive officers are reported in the "Non-Equity Incentive Plan Compensation" column of the "2025 Summary Compensation Table."

(3) The amounts reported in columns (f), (g) and (h) reflect PSU awards granted on February 18, 2025. The terms and conditions of these awards are described in the narrative following this table.

(4) The amounts reported in column (j) reflect nonqualified stock options granted on February 18, 2025. The terms and conditions of these awards are described in the narrative following this table.

(5) The stock options granted on February 18, 2025 have an exercise price of $230.29 per share, equal to the average of the high and low trading prices of shares of the Company's common stock on February 14, 2025, the trading date immediately preceding the date of grant, determined using Black-Scholes. The closing market price of the Company's common stock on the date of grant was $230.14 per share, which was lower than the stock option exercise price.

(6) The aggregate grant date fair value reported for the PSU awards, as calculated in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures, may differ from the value of the PSUs calculated based on the fair market value of the Company's common stock and is based on performance at the target level. The assumptions used in calculating the amounts reported for awards granted prior to 2025 are included in footnote 9 captioned "Stock Benefit Plans" to the Company's audited financial statements for the relevant fiscal year, included in the Company's Annual Reports on Form 10-K previously filed with the SEC.

Stock Options

Stock options represent the right to purchase a specified number of shares of the Company's common stock at a specified exercise price for a specified period of time. Stock options are scheduled to vest in four equal annual installments beginning on the first anniversary of the grant date, with earlier vesting and a shortened exercisability period in the event of death, disability and specified terminations of employment. The stock options granted to the

## Executive Compensation (Continued)
named executive officers on February 18, 2025 are scheduled to vest on February 18, 2026, 2027, 2028 and 2029 and will expire no later than February 17, 2035.

Stock options granted in 2025 have an exercise price equal to the average of the high and low trading prices of the Company's common stock on the trading day immediately preceding the grant date.

Performance Stock Unit Awards

A PSU award represents a promise to deliver, as soon as practicable after the end of the performance period, a number of shares of the Company's common stock ranging from 0% to 200% of the number of PSUs vested, based on performance as determined by the Compensation Committee. The performance measure for PSU awards is adjusted EPS growth as modified for executive compensation purposes and measured on a three-year annualized growth rate basis. PSU awards also include a modifier based on the Company's three-year TSR versus S&P 500 constituents. Additional information about the EPS performance factor and relative TSR modifier is provided in the "Annual LTI Awards" section on page 43 of the Compensation Discussion and Analysis. The PSU awards granted to the named executive officers on February 18, 2025 are scheduled to vest on February 28, 2028, with full or pro-rata vesting in the event of death, disability and specified terminations of employment. PSU awards include the right to payment of dividend equivalents for each share of common stock that is paid in respect of a vested PSU. Dividend equivalents that relate to PSU awards that do not vest or are forfeited also will be forfeited. Holders of PSU awards have no right to vote the shares of common stock subject to the award.

The treatment of these awards upon termination of employment or a change in control of the Company is described in further detail in "Potential Payments Upon Termination or Change in Control" on page 66.

Outstanding Restricted Stock Unit Awards

An RSU represents a promise to deliver a share of the Company's common stock as soon as practicable after vesting. RSU awards vest on a full or pro-rata basis in the event of death, disability and specified terminations of employment. RSU awards include the right to payment of dividend equivalents for each share of common stock that is paid in respect of a vested RSU. Dividend equivalents that relate to RSU awards that do not vest or are forfeited also will be forfeited. Holders of RSU awards have no right to vote the shares of common stock subject to the award.

The Company has not granted annual RSU awards to senior executives since 2019.

(4) Represents the number of shares to be received in respect of PSU awards assuming the achievement of maximum performance for the 2023 and 2024 PSU awards and target performance for the 2025 PSU award. The PSU awards granted in February 2023 vested on February 28, 2026, and PSU awards granted in February 2024 and February 2025 will vest on February 28, 2027 and February 28, 2028, respectively, and will be paid in a number of shares of the Company's common stock determined based on actual performance over the applicable three-year performance period. Our adjusted EPS growth rates as modified for executive compensation purposes for 2023, 2024 and 2025 were determined by the Compensation Committee in the first quarter after the end of the year. As of December 31, 2025, performance was tracking above target payout level for the 2023 and 2024 PSU awards and below target for the 2025 PSU awards. If the Company does not attain the maximum performance for the 2023 and 2024 PSU awards or target performance for the 2025 PSU award over the applicable three-year performance period, the number of shares received by the named executive officers upon settlement will be lower. The number of deliverable shares will range from 0% to 200% of the number of PSUs vested. See the "Performance Results for Our 2023 PSU Awards" section on page 46 of the Compensation Discussion and Analysis and the narrative following the "2025 Grants of Plan-Based Awards Table" above with respect to the 2025 PSU awards granted to the named executive officers.

Defined Benefit Retirement Program

The Company discontinued future service accruals effective December 31, 2016 in the tax-qualified Marsh & McLennan Companies Retirement Plan, the nonqualified Benefit Equalization Plan and the nonqualified Supplemental Retirement Plan (collectively, the "United States Defined Benefit Retirement Program"). The Benefit Equalization Plan is a restoration plan that provides those participants subject to certain Internal Revenue Code limitations with retirement benefits on a comparable basis to those provided to employees who are not subject to such limitations. The Supplemental Retirement Plan provides for an enhanced benefit for a select group of highly compensated employees. Mr. McGivney, Mr. Tomlinson and Mr. Klisura participate in the United States Defined Benefit Retirement Program. Mr. Doyle and Mr. South are not eligible to participate in the United States Defined Benefit Retirement Program because they did not meet the eligibility requirements to join the retirement program prior to December 31, 2016.

For participants who are eligible for these plans, annual benefits payable at age 65 in the form of a single-life annuity are determined generally by the following formula:

• 2.0% of eligible salary for each of the first 25 years of eligible benefit service through December 31, 2016; plus

• 1.6% of eligible salary for each of the next five years of eligible benefit service through December 31, 2016; plus

• 1.0% of eligible salary for each year of eligible benefit service over 30 years through December 31, 2016.

The above sum is reduced by an amount representing a portion of the participant's estimated Social Security benefit. Participants who are at least age 65 are eligible for normal retirement benefits and participants who have attained five years of vesting service and are at least age 55 are eligible for early retirement benefits. Mr. McGivney, Mr. Tomlinson and Mr. Klisura are eligible for early retirement benefits. Benefits under the United States Defined Benefit Retirement Program vest upon the earliest of (i) a participant's attainment of five years of vesting service, (ii) attainment of age 65 or (iii) a change in control of the Company. Mr. McGivney, Mr. Tomlinson and Mr. Klisura currently have a vested benefit under the United States Defined Benefit Retirement Program.

The present value of the accumulated pension benefits of the named executive officers who participate in these plans as of the end of 2025, as well as other information about each of our defined benefit retirement plans, is reported in the table below. Assumptions used in the calculation of these amounts, other than retirement age, are included in footnote 8 to the Company's audited financial statements for the fiscal year ended December 31, 2025, included in

## Executive Compensation (Continued)
the Company's Annual Report on Form 10-K filed with the SEC on February 9, 2026. The assumed retirement age used for purposes of this table is 65 years for all named executive officers who participate in these plans. Benefits under the tax-qualified Marsh & McLennan Companies Retirement Plan are generally paid as a monthly annuity for the life of the retiree and his or her designated survivor, if the participant has elected to be paid on a joint and survivor basis. The Company's policy for funding its obligation under the tax-qualified plan is to contribute amounts at least sufficient to meet the funding requirements set forth in applicable law. The Company is not required to, and does not, fund any of its obligations to the named executive officers who participate in these plans under any of its nonqualified defined benefit retirement plans.

(1) Represents years of benefit accrual service as of December 31, 2016.

(2) Assumptions used in the calculation of these amounts, other than retirement age, which has been assumed for purposes of this table to be 65 years for all of the named executive officers, are included in footnote 8 to the Company's audited financial statements for the fiscal year ended December 31, 2025, included in the Company's Annual Report on Form 10-K filed with the SEC on February 9, 2026. The U.S. Retirement Program provides a survivor benefit, in the form of a monthly annuity, to a qualifying spouse or domestic partner upon the death of a vested participant. The present value of this survivor benefit in the event of death on December 31, 2025 was $590,469 for Mr. McGivney, $84,494 for Mr. Tomlinson and $943,498 for Mr. Klisura. The total amounts reported in this column may not equal the sum of amounts reflected due to rounding to the nearest whole dollar as required by SEC rules.

(3) Mr. McGivney, Mr. Tomlinson and Mr. Klisura are eligible for an early retirement benefit. Their early retirement benefits are separately quantified in the table included in the "Potential Payments Upon Termination or Change in Control" section on page 66.

2025 Nonqualified Deferred Compensation Table

The SSIP is a nonqualified defined contribution plan that coordinates with the 401(k) Plan to give eligible participants the opportunity to defer compensation on a pre-tax basis in addition to what is allowed under the tax-qualified plan.

Under the SSIP, selected participants who have reached any one of the limitations set forth in the Internal Revenue Code under the 401(k) Plan may, at their election, defer up to 30% of their base salary and notionally invest this amount in any or all of the plan's notional investment alternatives. These alternatives consist of a variety of mutual funds and units of the Company's common stock. Participants in the SSIP may change their investment elections at any time with respect to future deferrals. Changes to existing balances are limited to once per calendar month. Additionally, once a participant notionally invests an amount in units of the Company's common stock, that amount cannot be reallocated to any other notional investment.

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

## Executive Compensation (Continued)
After a participant completes one year of service with the Company, the Company provides matching credits at the same rate as the 401(k) Plan. Effective January 1, 2017, eligible participants who are employed by an eligible participating company and have completed one year of service receive a 4% fixed company credit with respect to their base salary over the Internal Revenue Service limit on compensation that may be considered under the 401(k) Plan, whether or not they elect to make employee deferrals to the SSIP.

Participants are not permitted to make withdrawals from their accounts while they are employed by the Company. Participants are generally entitled to payment of their accounts after their employment ends, including upon retirement, death or disability in a lump sum or annual installments over 2 to 15 years.

All of the named executive officers were eligible to participate in the SSIP in 2025.

(1) Amounts reported in this column are also reported in the "All Other Compensation" column in the "2025 Summary Compensation Table" on page 57.

(2) Aggregate earnings are based upon the performance of a variety of mutual funds and shares of the Company's common stock. Because these earnings are based upon actual market performance, they are not considered above-market or preferential for purposes of SEC rules. Therefore, none of the amounts reported in this column are reportable in the "2025 Summary Compensation Table" on page 57.

Potential Payments Upon Termination or Change in Control

The following table sets forth the estimated payments and benefits to be provided to the named executive officers in the event of the specified terminations of employment, including following a change in control of the Company. In accordance with SEC rules, this table assumes that the relevant triggering event occurred on December 31, 2025, the last business day of the last completed fiscal year, and that the market price of the Company's common stock was the closing stock price as of December 31, 2025 ($185.52 per share), the last trading day of 2025.

The employment letter for each named executive officer provides that he/she will participate in the Company's Senior Executive Severance Pay Plan. In general, the Senior Executive Severance Pay Plan provides for cash severance in the event of an involuntary termination of employment without "cause" (as described in "Termination of Employment" below) or, within the two-year period following a change in control of the Company, either by the successor entity without cause or by the participant for a termination of employment for "good reason" (as described in "Termination of Employment" below). In addition, each such named executive officer is eligible for specified payments and benefits upon death or "disability" (as described in "Termination of Employment" below).

Cash severance under the Senior Executive Severance Pay Plan is paid in a lump sum equal to:

• one times annual base salary;

• one times the average of the annual bonuses paid to the participant for each of the three prior calendar years; and

• a pro-rata bonus for the year of termination.

The Senior Executive Severance Pay Plan also provides 12 months of outplacement services and continued medical and dental coverage for 12 months at active employee rates. Severance payments and benefits are conditioned on a participant having executed a waiver and release of claims in favor of the Company (including restrictive covenants). The cash severance amounts included in the following table reflect the employment arrangements in effect on December 31, 2025.

The terms and conditions of equity-based awards provide for full or pro-rata vesting in the event of death, disability and specified terminations of employment.

(a) Reflects amounts payable by the Company in the form of a lump sum as soon as practicable following termination of employment, subject to the individual's execution of a waiver and release of claims (including restrictive covenants) for the benefit of the Company.

(b) "Pro-Rata Bonus" amounts, if any, are payable by the Company at the same time annual bonuses for the applicable year are paid to the Company's senior executives generally, subject to the individual's execution of a waiver and release of claims (including restrictive covenants) for the benefit of the Company.

(c) Total amounts reported in this column may not equal the sum of amounts reflected in the preceding columns due to rounding to the nearest whole dollar as required by SEC rules.

(2) Reflects equity-based awards, with respect to the Company's common stock, outstanding as of December 31, 2025. The values for 2023, 2024 and 2025 PSU awards depend on the termination reason. For certain events such as retirement (i.e., age and service vesting), the values are based on results as determined by the Compensation Committee and 8% EPS growth for the remaining years of the award period for each award. For events in which the vesting of equity-based awards accelerates, such as death, the values are based on performance for abbreviated award periods.

(3) Each of the named executive officers is eligible to continue receiving Company-sponsored health insurance for 12 months following certain terminations of employment. To receive such benefits, a named executive officer is required to contribute at the same level as similarly situated active employees. Each of the named executive officers is eligible to receive outplacement services for a period of 12 months.

(4) The amounts reported in this column, where applicable, include the 401(k) Plan matching contributions made by the Company that would vest in the event of death or permanent disability (as defined the Company's Long-Term Disability Plan).

## Executive Compensation (Continued)
(5) Mr. McGivney, Mr. Tomlinson and Mr. Klisura are eligible for early retirement, as indicated in the "Defined Benefit Retirement Program" section on page 64. If Mr. McGivney had retired from the Company effective December 31, 2025, the present value of his accumulated pension benefits would have been $775,357 If Mr. Tomlinson had retired from the Company effective December 31, 2025, the present value of his accumulated pension benefits would have been $88,959. If Mr. Klisura had retired from the Company effective December 31, 2025, the present value of his accumulated pension benefits would have been $1,654,306. In addition, Mr. McGivney, Mr. Tomlinson and Mr. Klisura would have been entitled to payment of their account balances under the 401(k) Plan and the SSIP. These amounts are not reflected in the total set forth in this column. Mr. Doyle and Mr. South are not eligible to participate in the United States Defined Benefit Retirement Program because they did not meet the eligibility requirements to join the retirement program prior to December 31, 2016.

(6) Total amounts reported in this column may not equal the sum of amounts reflected in the preceding columns due to rounding to the nearest whole dollar as required by SEC rules.

Termination of Employment

Upon any termination of employment, including a termination for "cause" or without "good reason," a named executive officer will receive any accrued pay and regular post-employment payments and benefits under the terms of the Company's applicable plans. The amounts reported in the table above do not include payments and benefits that are provided on a nondiscriminatory basis to eligible employees upon termination of employment, including:

• base salary through the date of termination and accrued but unused vacation time;

• post-employment group medical benefit continuation at the employee's cost;

• welfare benefits provided to eligible U.S. retirees;

• distributions of defined benefit plan benefits, whether or not tax-qualified (our U.S. defined benefit retirement program is described in the "Defined Benefit Retirement Program" section, on page 64);

• distributions of tax-qualified defined contribution plans and nonqualified deferred compensation plans (the nonqualified deferred compensation plans are described in the "2025 Nonqualified Deferred Compensation Table" section, on page 65); and

• vested benefits.

The Senior Executive Severance Pay Plan defines "cause" as a participant's: (i) willful failure to substantially perform the duties consistent with his or her position which is not remedied within 10 days after receipt of written notice from the Company specifying such failure; (ii) willful violation of any written Company policy, including, but not limited to, the Company's Code of Business Conduct & Ethics; (iii) commission at any time of any act or omission that results in a conviction, plea of no contest, plea of nolo contendere or imposition of unadjudicated probation for any felony or crime involving moral turpitude; (iv) unlawful use (including being under the influence) or possession of illegal drugs; (v) gross negligence or willful misconduct which results in, or could reasonably be expected to result in, a material loss to the Company or material damage to the reputation of the Company; or (vi) violation of any statutory or common law duty of loyalty to the Company, including the commission at any time of any act of fraud, embezzlement or material breach of fiduciary duty against the Company.

The Senior Executive Severance Pay Plan defines "good reason" as: (i) a material reduction in the participant's base salary; (ii) a material reduction in the participant's annual incentive opportunity (including a material adverse change in the method of calculating the participant's annual incentive); (iii) a material diminution of the participant's duties, responsibilities or authority; or (iv) a relocation of more than 50 miles from the participant's office location in effect immediately prior to the change in control of the Company. This definition of "good reason" only applies during the 24-month period following a change in control of the Company.

The employment letter for each named executive officer defines "permanent disability" as occurring when it is determined (by the Company's disability carrier for the primary long-term disability plan or program applicable to the named executive officer because of his or her employment with the Company) that the named executive officer is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

Change in Control

As described in the "Change-in-Control Arrangements" section on page 51, the terms of our outstanding and unvested equity-based awards contain a "double-trigger" change-in-control vesting provision, which requires a change in control of the Company followed by a specified termination of employment for accelerated vesting to

*Notice of Annual Meeting and 2026 Proxy Statement* **\| Marsh & McLennan Companies, Inc. \| 69** 

------

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

## Executive Compensation (Continued)
occur. Under the double-trigger provision, a change in control of the Company by itself would not cause an employee's equity-based award to vest, so long as the award is assumed or replaced on equivalent terms. In that case, vesting would continue pursuant to the award's original vesting schedule unless, in addition to the change in control, the employee's employment terminates without "cause" or for "good reason" during the 24 months following the change in control.

The change-in-control provisions included in our Senior Executive Severance Pay Plan also require both "double-trigger" events to occur for payments and benefits to be provided.

We do not provide change-in-control excise tax payments, reimbursements or "gross-ups" to any of our senior executives under any plan or arrangement. Cash severance payments are not eligible for any tax reimbursement benefit.

We use the same definition of "change in control" in the equity incentive plans and the Senior Executive Severance Pay Plan.

The definitions of "cause" and "good reason" in equity-based awards for the named executive officers are similar to those described above in "Termination of Employment."

Restrictive Covenants

Each of the named executive officers is subject to nonsolicitation covenants that prohibit the executive from:

• soliciting any customer or client with respect to a competitive activity; and

• soliciting or employing any employee for the purpose of causing the employee to terminate employment.

Each of the named executive officers is also subject to noncompetition covenants that prohibit the executive from engaging in a competitive activity.

For Mr. Doyle, the noncompetition and nonsolicitation period ends 24 months after the date of termination of employment. For the other named executive officers, this period ends 12 months after the date of termination of employment.

In addition, at all times prior to and following termination of employment, the named executive officers are subject to a perpetual confidentiality covenant.

## Audit

## Item 3:

## Ratification of Selection of Independent Registered Public Accounting Firm
The Audit Committee and the Board believe that the continued retention of Deloitte & Touche to serve as the Company's independent registered public accounting firm is in the best interests of the Company and its investors based on the Audit Committee's level of satisfaction with the quality of services provided by Deloitte & Touche and consideration of factors described below.

Appointment

The Audit Committee is directly responsible for the appointment, compensation and oversight of the independent registered public accounting firm retained to audit the Company's financial statements. The Audit Committee has appointed Deloitte & Touche LLP as the Company's independent registered public accounting firm for the 2026 fiscal year. Deloitte & Touche was first retained as the independent registered accounting firm of the Company in 1989.

Review and Approval: Compensation, Leadership, Composition and Organization

The Audit Committee is responsible for reviewing and approving the compensation of Deloitte & Touche in connection with the annual appointment process. As part of its regular process, the Audit Committee annually reviews and approves the leadership, composition and organization of the external audit team. The Audit Committee also periodically considers the rotation of the independent external audit firm and whether to commence an audit tender process, considering such factors as the tenure, fees, independence and capabilities of the external auditor. Further, in conjunction with the mandated rotation of the independent registered public accounting firm's lead audit partner, the Audit Committee and its chairman are directly involved in the review and approval of Deloitte & Touche's lead audit partner.

2025 Audit and Other Services

Deloitte & Touche will audit our consolidated financial statements for fiscal year 2026 and perform other services. Deloitte & Touche acted as the Company's independent registered public accounting firm for the year ended December 31, 2025. A Deloitte & Touche representative will be present at the 2026 annual meeting of stockholders and will have an opportunity to make a statement and be available to respond to appropriate questions.

Ratification as Good Corporate Practice

Although ratification is not required by the Company's bylaws or otherwise, the Board is submitting this proposal as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another independent auditor. Even if the selection is ratified, the Audit Committee may select a different auditor at any time during the year if it determines that this would be in the best interests of the Company and its stockholders.

Audit Committee Pre-Approval Policy

The Audit Committee has adopted a policy regarding pre-approval of audit and non-audit services provided by Deloitte & Touche to the Company and its subsidiaries. The policy provides the guidelines necessary to adhere to the Company's commitment to auditor independence and compliance with relevant rules and regulations relating to auditor independence. The policy contains a list of prohibited non-audit services, and sets forth four categories of permitted services (Audit, Audit-Related, Tax and Other), listing the types of permitted services in each category. All of the permitted services require pre-approval by the Audit Committee. In lieu of Audit Committee pre-approval on an engagement-by-engagement basis, each category of permitted services, with reasonable detail as to the types of services contemplated, is pre-approved as part of the annual services performed by Deloitte as approved by the Audit Committee. Permitted services not contemplated during the budget process must be presented to the Audit Committee for approval prior to the commencement of the relevant engagement. The Audit Committee chair or, if he is not available, any other member of the Committee, may grant approval for any such engagement if approval is required prior to the next scheduled meeting of the Committee. Any such approvals are reported to the Audit Committee at its next meeting. At least twice a year, the Audit Committee is presented with a report showing amounts billed by the independent registered public accounting firm compared to the budget approvals for each of the categories of permitted services. The Committee reviews the suitability of the pre-approval policy at least annually.

Audit Committee Report

The Audit Committee of the Board of Directors is comprised of the five directors named below. Each member of the Committee is independent as required by the Company, the listing standards of the NYSE and the SEC's audit committee independence rules. The primary function of the Audit Committee is to assist the Board of Directors in its oversight responsibilities with respect to the integrity of the Company's financial statements; the qualifications, independence and performance of the Company's independent auditors; the performance of the Company's internal audit function; and compliance by the Company with legal and regulatory requirements. The Committee operates pursuant to a charter approved by the Board of Directors.

## Audit (Continued)
Management is responsible for the Company's financial statements, the overall reporting process and the system of internal control, including internal control over financial reporting. Deloitte & Touche LLP, our independent registered public accounting firm, is responsible for conducting annual audits and quarterly reviews of the Company's financial statements and expressing an opinion as to the conformity of the annual financial statements with generally accepted accounting principles in the United States and expressing an opinion on our internal control over financial reporting as of the end of our fiscal year.

In performing their oversight responsibility, members of the Audit Committee rely without independent verification on the information provided to them and on the representations made by management and Deloitte & Touche. The members of the Committee are not professionally engaged in the practice of auditing or accounting and are not experts in the fields of accounting or auditing, including in respect of auditor independence.

During 2025, the Audit Committee executed its oversight function through a series of meetings and teleconferences with management and Deloitte & Touche. The Audit Committee also reviewed and discussed with management and Deloitte & Touche the Company's audited financial statements as of and for the year ended December 31, 2025, as well as matters related to internal control over financial reporting and the processes that support the Company's reporting of financial results. The Committee also discussed with Deloitte & Touche the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Committee has received the written disclosures and the letter from Deloitte & Touche required by applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence, has considered whether the provision of other non-audit services by Deloitte & Touche to the Company is compatible with maintaining Deloitte & Touche's independence and has discussed with Deloitte & Touche that firm's independence.

Based upon the review and discussions described in this report, the Committee recommended to the Board, and the Board approved, that the audited financial statements and management's annual report on internal control over financial reporting be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC. The Committee has also selected Deloitte & Touche as the Company's independent registered public accounting firm for 2026. The Board of Directors concurred with that selection and has recommended this selection to the Company's stockholders for ratification.

DIRECTOR COMPENSATION

Executive Directors

Executive directors (currently only Mr. Doyle) receive no compensation for their service as directors.

Independent Directors

Independent directors receive a basic annual retainer and annual stock grant as compensation for their service as directors. Our Independent Chair and directors who serve as the chair of a committee also receive a supplemental annual retainer. The Board's compensation year runs from June 1 through May 31.

In 2025, the Board reviewed the independent director compensation arrangements, which have been unchanged since 2023, and requested and received advice from an independent consulting firm, Pay Governance LLC. The Board revised the basic annual retainer, supplemental retainer for the chair of the Audit Committee and annual stock grant for independent directors effective June 1, 2025 as shown in the table below.

(1) The amounts in this "Fees Earned or Paid in Cash" column reflect payments of the basic annual retainer and any supplemental retainer made during fiscal 2025, as set forth in more detail below. The chair of the Audit Committee received $30,000 for such service. The chair of the Compensation Committee received $25,000 for such service, the chairs of the Directors & Governance, Finance and Business Responsibility committees each received $20,000 for such service, and the Independent Chair received $200,000 for such service. The committee chairs compensated during fiscal 2025 were: Ms. Hopkins (Finance), Ms. Ingram (Business Responsibility), Mr. Mills (Compensation), Mr. Anderson (Audit), Mr. Schapiro (Directors and Governance), and Mr. Yates (Business Responsibility). Committee members other than the chairs receive no additional compensation for service on a committee.

Mr. Fanjul and Mr. Mills elected to receive their quarterly payments in the form of the Company's common stock. Mr. Schapiro, and Mr. Yates elected to receive their quarterly payments in the form of the Company's common stock on a deferred basis. Ms. Lute elected to receive 75% of her quarterly payments in the form of Company's common stock on a deferred basis. All of the other independent directors received these amounts in cash. <br>

(2) This column reflects the award of 929 shares of the Company's common stock to each independent director on June 1, 2025. The shares awarded to each director had an aggregate grant date fair value of $215,000, based on a per share price of $231.27, which was the average of the high and low prices on May 31, 2025, the trading day immediately preceding the grant date. The amounts shown in this column constitute the dollar amount recognized by the Company for financial statement reporting purposes for the fiscal year ended December 31, 2025, calculated in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. The actual value, if any, realized by our independent directors for these awards is a function of the value of shares if and when they vest. For additional information on how we account for equity-based compensation, see footnote 9 to the Company's audited financial statements for the fiscal year ended December 31, 2025, included in the Company's Annual Report on Form 10-K filed with the SEC on February 9, 2026. Mr. Anderson, Ms. Hopkins, Ms. Ingram, Ms. Lute, Mr. Schapiro, Mr. Siegmund and Mr. Yates elected to defer receipt of all of the shares awarded to them.

As of December 31, 2025, the aggregate number of deferred shares held for the account of each current independent director who previously elected to defer shares was as follows: Mr. Anderson, 15,564 shares, Ms. Hopkins, 19,850 shares, Ms. Ingram, 7,653 shares, Ms. Lute, 7,157 shares, Mr. Schapiro, 87,650 shares, Mr. Siegmund, 938 shares and Mr. Yates, 10,492 shares. Dividend equivalents on these deferred shares are reinvested into additional deferred shares for the account of the independent director. <br>

(3) The Company maintains a matching gift program for colleagues and directors, pursuant to which the Company matches, on a dollar-for-dollar basis, certain charitable contributions. For 2025, the Company matched up to $1,000 per colleague or director. No charitable contributions were matched for directors in 2025.

(4) Mr. Broussard was elected to the Board effective July 9, 2025.

(5) Mr. Fanjul did not stand for re-election at the May 2025 annual meeting.

(1) This column reflects shares subject to outstanding and unexercised options granted during the last ten years under the *Amended and Restated 2020 Incentive and Stock Award Plan* and the *2011 Incentive and Stock Award Plan.* This column also contains information regarding the equity awards specified in notes (4) and (6) below. There are no warrants or stock appreciation rights outstanding.

(2) The number of shares that may be issued during the current offering periods under stock purchase plans, and the weighted-average exercise price of such shares, are uncertain and consequently not reflected in columns (a) and (b). The number of shares to be purchased will depend on the amount of contributions plus any interest accumulated under these plans as of the close of each purchase period during the current offering periods and the value of a share of Company common stock on each purchase date. An estimate of the number of shares subject to purchase during the current offering period for the *1999 Employee Stock Purchase Plan* is 462,682 shares. An estimate of the number of shares subject to purchase during the current offering periods which mature in 2025 for the *Stock Purchase Plan for International Employees, Stock Purchase Plan for French Employees, Save as You Earn Plan (U.K.), Irish Savings Related Share Option Scheme (2001)* and *Share Participation Schemes for employees in Ireland* is 244,434 shares *.* The shares remaining available for future issuance shown in column (c) include any shares that may be acquired under all current offering periods for these stock purchase plans. Further information regarding shares available for issuance under these plans is set forth in the first bullet of note (5) and in note (7) below.

(3) The weighted-average exercise price in column (b) does not take into account the awards referenced in notes (4) and (6) below. There are no outstanding options under equity compensation plans not approved by stockholders.

(4) Includes 3,957,059 shares that may be issued to settle outstanding restricted stock unit, deferred stock unit and deferred bonus unit awards under the *Amended and Restated 2020 Incentive and Stock Award Plan*, the *2011 Incentive and Stock Award Plan* and the *2000 Senior Executive Incentive and Stock Award Plan* and predecessor plans and programs as well as other deferred compensation obligations under the *Directors' Stock Compensation Plan* and the *Supplemental Savings & Investment Plan*, a nonqualified deferred compensation plan providing benefits to colleagues whose benefits are limited under the Company's *401(k) Savings & Investment Plan*.

For the two stock purchase plans, colleagues may acquire shares at a discounted purchase price (which may be no less than 95% of the market price of the stock on the relevant purchase date) on four quarterly purchase dates within each one-year offering period with the proceeds of their contributions plus interest accumulated during the respective quarter. For the *Irish Savings Related Share Option Scheme (2001)*, eligible employees may elect to contribute to these plans through regular payroll deductions over an offering period that varies by plan from one to five years. On each purchase date, generally the end of the offering period, participants may receive their contributions plus interest in cash or use that amount to acquire shares of stock at a discounted purchase price, which may be no less than 95% of the market price of the stock at the beginning of the offering period.

• 15,246,943 shares available for future awards under the *Amended and Restated 2020 Incentive and Stock Award Plan.* Awards may consist of stock options, stock appreciation rights, restricted stock, restricted stock units, stock bonuses and stock awards in lieu of cash awards, dividend equivalents and other stock-based or unit-based awards.

Pay Versus Performance

One of the key principles by which we govern our executive compensation program is to support a solid performance culture through short-term and long-term variable compensation. In 2025, performance-based compensation represented 83% or more of each of our named executive officers' target total direct compensation. As a result of this weighting toward variable, performance-based compensation, the financial performance of the Company, including stock performance, plays an integral role in determining compensation actually paid to each of our named executive officers each year.

CEO Pay Ratio

In accordance with Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K of the Securities Act, we are required to provide information regarding the relationship-between the annual total compensation of our CEO, Mr. Doyle, and the annual total compensation of our median employee (excluding for purposes of this disclosure, our CEO) for our last completed fiscal year, which ended December 31, 2025. The ratio of the annual total compensation for our CEO (Mr. Doyle) compared to the median of the annual total compensation of all of our employees (excluding our CEO) for 2025 is 330. We believe this ratio to be a reasonable estimate, based upon the assumptions and adjustments described below.

The ratio for 2025 is based on the annual total compensation of the Company's median employee (excluding our CEO) and our CEO (as disclosed in the 2025 Summary Compensation Table in this proxy statement), as follows:

---

| | |
|:---|:---|
| •  Median employee:<br>| &nbsp;&nbsp;&nbsp;&nbsp;$76092 |
| •  CEO:<br>| $25051051 |

---

We identified the median employee based on total cash compensation, including base salary for 2025 and cash incentive compensation for 2024, for all individuals, excluding our CEO, who were employed by the Company (including our consolidated subsidiaries) on the median employee determination date (December 31, 2025). Our total number of employees on the median employee determination date, including U.S. and non-U.S. employees, was approximately 95,000.

We annualized the base salary of permanent full-time and part-time employees hired in 2025 and of employees on a leave of absence. We did not annualize the base salary of temporary employees.

For employees paid other than in U.S. dollars, we converted their compensation to U.S. dollars using the Company's budgeted currency exchange rates for 2025.

After identifying the median employee, we calculated annual total compensation for that employee for 2025 using the same methodology used to calculate the amount reported for our named executive officers in the "Total" column of the 2025 Summary Compensation Table.

The pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K and based upon our reasonable judgment and assumptions. The SEC rules do not specify a single methodology for identification of the median employee or calculation of the pay ratio, and other companies may use assumptions and methodologies that are different from those used by us in calculating their pay ratio. Accordingly, the pay ratio disclosed by other companies may not be comparable to our pay ratio as disclosed above.

Information about Our Annual Meeting and Solicitation of Proxies

Why Have I Received a Notice Regarding Internet Availability of Proxy Materials Instead of Printed Copies of These Materials in the Mail?

In order to reduce paper and postage costs, and in accordance with SEC rules, we have elected to furnish our proxy materials to stockholders over the Internet. Most stockholders are receiving by mail a Notice of Internet Availability of Proxy Materials ("Notice"), which provides general information about the annual meeting, the address of the website on which our proxy statement and annual report are available for review, printing and downloading and instructions on how to submit proxy votes. For those who wish to receive their materials in a different format (e.g., paper copy by mail or electronic copy by e-mail), the Notice contains instructions on how to do so. Stockholders who are current employees of the Company or who have elected to receive proxy materials via electronic delivery will receive via e-mail the proxy statement, annual report and instructions on how to vote.

How May I Obtain Electronic Delivery of Proxy Materials in the Future?

Stockholders who have elected to receive paper copies of the proxy materials will receive them by mail. If you are a stockholder of record and would prefer to receive electronic delivery, you may choose electronic delivery by following the instructions provided when you vote over the Internet. If you are a beneficial owner who holds shares in street name, it is likely that you will have the option to choose future electronic delivery of proxy materials when you vote over the Internet. Otherwise, please contact your broker or other intermediary holder of record for information regarding electronic delivery of proxy materials.

Who Can Vote on the Matters Being Decided at the Annual Meeting?

With respect to each matter properly brought before the meeting, each stockholder who held shares as of the close of business on March 23, 2026, which we refer to as the record date, is entitled to one vote, at the annual meeting or by proxy, for each share of common stock held as of that date. As of the record date, there were outstanding 483,095,948 shares of Marsh common stock entitled to vote.

Stockholders of Record

If, as of the close of business on the record date, your shares were registered directly in your name with our transfer agent, Equiniti Trust Company, you are a stockholder of record. As a stockholder of record, you may vote during the meeting or by proxy. The Company is incorporated in Delaware, and in accordance with Delaware law, a list of the Company's common stockholders of record as of the record date will be available for inspection for at least ten days prior to the annual meeting by contacting Investor Relations by telephone at (212) 345-5411 or by e-mail <u>marsh.investor.relations@marsh.com</u>.

Beneficial ("Street Name") Stockholders

If, as of the close of business on the record date, your shares were not held directly in your name but rather were held in an account at a brokerage firm, bank or similar intermediary organization, then you are the beneficial holder of shares held in "street name." The intermediary is considered to be the stockholder of record for purposes of voting during the annual meeting. As a beneficial owner, you have the right to direct the intermediary how to vote the shares held in your account.

How Do I Vote?

Whether you hold shares as a stockholder of record or beneficial owner, you may direct how your shares are voted without participating in the annual meeting. Even if you plan to attend the annual meeting, we encourage you to vote in advance of the meeting. If you are a stockholder of record, you may vote by submitting a proxy in accordance with the instructions included in your Notice or on your proxy card. If you are a beneficial owner holding shares in street name, you may vote by submitting voting instructions to your broker, bank, trustee or other intermediary in accordance with the voting instruction form provided to you. Executors, administrators, trustees, guardians, attorneys

You May Vote in the Following Manner:

By Telephone or the Internet

You may vote your shares via telephone or the Internet as instructed in the Notice or the proxy card, depending on how you received the proxy materials. The telephone and Internet procedures are designed to authenticate a stockholder's identity, to allow stockholders to vote their shares and to confirm that their instructions have been properly recorded.

By Mail

Stockholders who receive hard copies of the proxy materials may choose to vote by mail and, if you so choose, should complete, sign and date your proxy card or voting instruction card and mail it in the pre-addressed envelope included with the proxy materials. Note that, if you are a stockholder of record and you sign and return a proxy, but do not specify how to vote, your shares will be voted by the proxies in accordance with the Board's recommendations, which will be in favor of our director nominees (Item 1); to approve, by nonbinding vote, the compensation of our named executive officers (Item 2) and in favor of the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm (Item 3).

Can I Vote My Shares at the Virtual Annual Meeting?

Yes. However, even if you plan to attend the meeting, we recommend that you vote in advance of the meeting. If you vote in advance and then attend the meeting, you can always change your vote at the meeting.

Stockholders may vote during the virtual annual meeting by logging into the meeting website and following the instructions on the website. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to vote during the meeting.

Can I Change My Vote?

Yes. Stockholders of record may revoke their proxy before it is voted at the annual meeting by (i) submitting a new proxy with a later date, (ii) voting at the annual meeting or (iii) delivering written notification of revocation before the annual meeting addressed to: Marsh, Attn: Corporate Secretary, 1166 Avenue of the Americas, New York, New York 10036-2774.

If you hold your shares in street name, you may change your vote by submitting new voting instructions to your broker or other intermediary, following the instructions they provided, before the annual meeting or by voting during the annual meeting.

How do I vote shares held in the Marsh & McLennan Companies or Marsh & McLennan Agency 401(k) Savings & Investment Plans?

If you are a participant in the Company's or Marsh & McLennan Agency's 401(k) Plan, you may direct the 401(k) Plan trustee how to vote your shares. Under the terms of the 401(k) Plan, the trustee votes all shares held by the 401(k) Plan, but each participant may direct the trustee how to vote the Company shares allocated to their 401(k) Plan account. If you own shares through the 401(k) Plan and do not submit voting instructions, the 401(k) Plan trustee will vote the shares in accordance with the Board's recommendations. To vote your shares held in 401(k) Plan, follow the instructions above.

Whether you hold shares as a stockholder of record or are a beneficial owner, we urge you to vote in advance by Internet, telephone or mail so that your vote will be counted in the event you later decide not to attend the annual meeting.

What Should I Do to Ask a Question at the Annual Meeting?

Prior to meeting

Stockholders may submit questions in advance of the meeting by visiting <u>proxyvote.com</u>. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to ask questions.

During the meeting

On the day of the meeting, stockholders must visit <u>www.virtualshareholdermeeting.com/MRSH2026</u> to ask questions during the meeting. Stockholders will need the 16-digit control number found on their proxy card, voting instruction form or notice they previously received to ask questions.

What are the Requirements to Conduct Business at the Annual Meeting?

In order to carry on the business of the annual meeting, we must have a quorum. This means at least a majority of the outstanding shares eligible to vote at the meeting must be present in person or represented by proxy at the annual meeting. Both abstentions and broker nonvotes (described below) are counted for the purpose of determining the presence of a quorum.

What are the Voting Requirements to Elect Directors and to Approve the Other Proposals Discussed in the Proxy Statement?

The voting standards applicable to the annual meeting are as follows:

Election of Directors

The Company's bylaws provide that in an uncontested election, a nominee will be elected if the number of votes cast "for" the nominee's election exceeds the number of votes cast "against" the nominee's election. Abstentions will not be included in the total number of votes cast and therefore will have no effect on the election's outcome. The election of directors is not considered a "routine" matter and thus brokers do not have discretionary authority to vote in the election of directors if they did not receive instructions from a beneficial owner. As a result, broker nonvotes will not be included in the total number of votes cast and therefore will have no effect on the election's outcome. (See "Significance of Broker Nonvotes" below.)

Our Governance Guidelines address the procedures to be followed if an incumbent director standing for reelection in an uncontested election fails to receive a majority of the votes cast. See "Director Election Voting Standard" on page 8.

Vote Required for Other Proposals

---

| | |
|:---|:---|
| &nbsp;&nbsp;&nbsp;&nbsp; Proposal | Vote Required |
| &nbsp;&nbsp;&nbsp; Item 2—Advisory (nonbinding) vote to approve named executive officer compensation | Majority of the voting power present in person or represented by proxy at the meeting and entitled to vote |
| &nbsp;&nbsp;&nbsp; Item 3—Ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm | Majority of the voting power present in person or represented by proxy at the meeting and entitled to vote |

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

## Additional Information (Continued)
In accordance with Delaware law, abstentions will be treated as present and entitled to vote for purposes of voting on these items, while broker nonvotes (described below) will not. Abstentions have the effect of a vote "against" each of the proposals. Broker nonvotes will have no effect on the outcomes of these proposals.

Significance of "Broker Nonvotes"

NYSE rules provide that, when a matter to be voted on at an annual meeting is "non-routine," a broker holding shares of record on behalf of a client may vote those shares only if the broker has received voting instructions from the client. The broker may submit a proxy on any routine matter, for which instructions were required but not provided, but when the broker refrains from voting on non-routine matters, a "broker nonvote" occurs. Shares subject to a broker nonvote are not counted as present or represented with respect to those matters, but are counted as present and represented for purposes of determining the presence of a quorum at the annual meeting. Under the rules of the NYSE, the election of directors (Item 1) and the nonbinding vote to approve the compensation of our named executive officers (Item 2) are considered non-routine.

Could Additional Matters be Decided at the Annual Meeting?

As of the date of this proxy statement, we do not know of any matters not described in this proxy statement that will be presented at the meeting. However, if any other matter shall properly come before the meeting, the persons named in the proxy will use their discretion to vote on such matter on behalf of shares for which proxies were submitted.

Who Conducts the Annual Meeting?

The Independent Chair acts as chairman of the annual meeting and has the authority to prescribe rules, regulations and procedures and take the other actions as appropriate for the proper conduct of the meeting. In doing so, the chairman has the discretion to establish reasonable rules for comments and questions during the meeting.

Who Will Count the Votes at the Annual Meeting?

One or more representatives of Broadridge Financial Solutions, Inc. will tabulate the votes and act as independent inspectors of election.

How Are Materials Provided to Stockholders Sharing the Same Address?

In order to reduce paper and postage costs, we have adopted a procedure approved by the SEC called "householding." Under this procedure, stockholders of record or who hold shares in certain employee benefit plan accounts and who share the same last name and reside at the same mailing address will receive one Notice or one set of proxy materials (if they have elected to receive hard copies of the proxy materials), unless one of the stockholders at that address has notified us that they wish to receive individual copies.

Stockholders who participate in householding continue to receive separate control numbers for voting and, in the case of those who receive hard copies of the proxy materials, separate proxy cards. Householding does not in any way affect dividend check mailings. We will deliver a separate set of proxy material upon request, as set forth below under "How May I Obtain Another Set of Proxy Materials?"

If you are a stockholder of record or hold our common stock in an employee benefit plan account and currently are subject to householding, but prefer to receive separate copies of proxy materials and other stockholder communications from the Company, you may revoke your consent to householding at any time by calling Broadridge Financial Solutions, Inc. toll-free at 1-866-540-7095 or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

Who will Bear the Cost of this Proxy Solicitation?

We are providing these proxy materials in connection with the solicitation made by the Company's Board of Directors of proxies to be voted at our annual meeting. We pay the expenses of preparing and distributing the proxy materials and soliciting proxies. We also reimburse brokers and other institutional record holders for their expenses in forwarding these materials to, and obtaining voting instructions from, beneficial owners of the Company's common stock.

In addition to the distribution of this proxy statement and instructions for voting at the annual meeting, proxies may be solicited personally, electronically or by telephone by our directors, officers and other colleagues at no additional compensation.

Notice of proxy access director nominees must be received no earlier than November 1, 2026 and no later than December 1, 2026.

Stockholder Proposals or Director Nominations, but Not for Inclusion in the Proxy Statement

To properly bring the nomination or other stockholder business before an annual meeting, the proponent must be a stockholder of record and comply with certain notice procedures. In the case of other stockholder business, the business must also be a proper matter for stockholder action in accordance with law, the Company's Certificate of Incorporation and the Company's bylaws. The notice must be delivered not earlier than 5:00 p.m. Eastern Time on January 21, 2027, and not later than 5:00 p.m. Eastern Time on February 20, 2027 and satisfy all applicable requirements in our bylaws.

## Exhibit A

## Marsh & McLennan Companies, Inc.
Reconciliation of Non-GAAP Measures—Actual as Reported

Twelve Months Ended December 31

(Millions) (Unaudited)

Overview

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (referred to in this release as in accordance with "GAAP" or "reported" results). The Company also refers to and presents certain additional non-GAAP financial measures, within the meaning of Regulation G and item 10(e) Regulation S-K in accordance with the Securities Exchange Act of 1934. These measures are: non-GAAP revenue, adjusted operating income (loss), adjusted operating margin, adjusted income, net of tax and adjusted earnings per share (EPS). The Company has included reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP in the following tables.

The Company believes these non-GAAP financial measures provide useful supplemental information that enables investors to better compare the Company's performance across periods. Management also uses these measures internally to assess the operating performance of its businesses and to decide how to allocate resources. However, investors should not consider these non-GAAP measures in isolation from, or as a substitute for, the financial information that the Company reports in accordance with GAAP. The Company's non-GAAP measures include adjustments that reflect how management views its businesses, and may differ from similarly titled non-GAAP measures presented by other companies.

In the first quarter of 2025, the Company changed its methodology to report adjusted operating income (loss), adjusted income, net of tax and adjusted EPS to exclude the impact of intangible amortization and other net benefit credits. Prior year results are presented using the new methodology for comparative purposes.

Adjusted Operating Income (Loss) and Adjusted Operating Margin

*Adjusted operating income (loss)* is calculated by excluding the impact of certain noteworthy items and identified intangible amortization expense from the Company's GAAP operating income (loss). The following tables reconcile *adjusted operating income (loss)* to GAAP operating income (loss) on a consolidated and reportable segment basis for the twelve months ended December 31, 2025 and 2024. The following tables also present adjusted operating margin. For the twelve months ended December 31, 2025 and 2024, *adjusted operating margin* is calculated by dividing the sum of adjusted operating income by consolidated or segment adjusted revenue. The Company's adjusted revenue used in the determination of *adjusted operating margin* is calculated by excluding the impact of certain noteworthy items from the Company's GAAP revenue.

(a) In the third quarter of 2025, the Company launched a three-year program, Thrive, which focuses on our brand strategy, delivering greater value to clients, accelerating growth and improving efficiency. The program will generate savings from process and automation efficiencies and optimization of our global operating model. Costs in 2025 relate primarily to severance and lease exit charges. Costs in 2024 included severance and lease exit charges for a restructuring program completed in 2024.

(b) Reflects change in the fair value of contingent consideration and deferred acquisition costs.

(c) Reflects one-time acquisition and disposition related retention and other costs.

(d) RIS in 2025 includes primarily a gain on the sale of a business and a gain on the remeasurement of an investment.

*Non-GAAP revenue* isolates the impact of foreign exchange rate movements and certain transaction-related items from the current period GAAP revenue. The non-GAAP revenue measure is presented on a constant currency basis, excluding the impact of foreign currency fluctuations. The Company isolates the impact of foreign exchange rate movements period over period, by translating the current period foreign currency GAAP revenue into U.S. Dollars based on the difference in the current and corresponding prior period exchange rates. Similarly, certain other items such as acquisitions and dispositions, including transfers among businesses, may impact period over period comparisons of revenue and are consistently excluded from current and prior period GAAP revenues for comparability purposes. Percentage changes, referred to as *non-GAAP underlying revenue*, are calculated by dividing the period over period change in non-GAAP revenue by the prior period *non-GAAP revenue*.

The following table provides the reconciliation of GAAP revenue to non-GAAP revenue:
