VOTING MATTERS

Key Governance Practices and Policies

During a period of active Board refreshment, nine new directors, including a new CEO and eight new independent directors, one of whom is now our Board Chair, joined the Board from 2022 through 2024. Our Board composition reflects a mix of gender, race, ethnicity, nationality, backgrounds, experiences and skill sets.

The figures in the above pie charts relate to our director nominees and are rounded to the nearest whole number.

The Board continually reviews and adapts its oversight structure to align with the critical needs of the business. Following the completion of the three-year remit of the Operational Transformation Committee at the end of 2024 in connection with the conclusion of the Company’s Operational Transformation Program ("Transformation Program"), the Board revisited its Committee structure and determined to maintain four Board Committees and restructured the Committees' responsibilities in a manner that it believes helps support the Company’s strategy.

Accordingly, effective January 1, 2025, the Board:

The Board maintained the Human Capital and Compensation Committee and Corporate Governance and Nominating Committee in their current forms, with no material changes to their remits.

Additionally, the Board elected Paul Reilly to replace Paul Thomas as its non-Executive Chair, effective as of the conclusion of the 2025 AGM in connection with Mr. Thomas’s departure from the Board.

The Board Committees assist the Board in overseeing, among other things, the following:

Refer to the section entitled “Corporate Governance – Willis Towers Watson Board Committees” for more information on the Board Committees’ responsibilities.

Approach: Our clients, colleagues and other stakeholders expect us to conduct our business with integrity and in an environmentally and socially responsible manner. We take these expectations seriously and, consistent with what we believe enhances long-term value, have embraced principles that are aligned with our business priorities and support the communities in which we operate across the globe. "Sustainability" is how we refer to our environmental, people and community and governance strategy that guides our internal operations. See Sustainability Oversight for more information on sustainability including management and board oversight of activities.

Management Oversight: The Company has a cross-functional management committee to coordinate and facilitate communication of the Company’s sustainability initiatives applicable to its own operations.

Board Oversight: The Board takes an approach that the most appropriate Committee maintains oversight over a particular issue rather than concentrating all sustainability initiatives into any one Committee. The Committees report to the Board on sustainability matters as appropriate.

To learn more about our sustainability principles, goals and related statements, and to review our Sustainability Report and SASB appendix and our TCFD disclosure, visit: www.wtwco.com/en-us/about-us/sustainability-report. The information on, or accessible through, our website and our other reports is not part of or incorporated by reference into this Proxy Statement and is current only as of the date it was first published.

We conduct a semi-annual shareholder outreach program whereby we reach out to shareholders holding at least a majority of our outstanding shares. Over the past several years, we have incorporated feedback from our shareholders into our executive compensation and governance programs.

Key Executive Compensation Practices and Policies

Proposal No. 1: Elect Directors

Our Board is responsible for overseeing our global business in a manner consistent with the respective fiduciary duties of each member of the Board. The Corporate Governance and Nominating Committee (the “Governance Committee”) continuously assesses the Board’s size and composition to determine if it is effective and represents the long-term interests of shareholders. As discussed further below, the Governance Committee believes that the slate of director nominees as a whole reflects the collective knowledge, integrity, reputation and leadership abilities, and the overall mix of skills, experience and attributes, that are appropriate for the Company’s governance and oversight. At the Governance Committee’s recommendation, the Board has nominated the persons listed in this Proposal No. 1 to serve until the next AGM unless they are removed or resign before that meeting.

The Board unanimously recommends a vote “FOR” the election of each of the directors.

Required Vote

Our directors are elected by way of separate resolutions, each of which requires the affirmative vote of a majority of the votes cast by shareholders at the 2026 AGM, and, upon their elections, will hold office until the next AGM unless they are removed or resign before that meeting. Any nominee for director who does not receive a majority of the votes cast is not elected to the Board.

Evolution of Board Composition and Structure

Over the past several years, the composition and structure of the Board substantially changed as the result of the Board's strategic refreshment process. As part of this multi-year succession planning program, including input from a third-party consulting firm, the Board:

This refreshment strategy balanced the importance of adding new directors to the Board while also facilitating onboarding by providing incoming directors with the opportunity to work with more tenured directors before the latter retire from the Board. The Board believes the right balance of skills, background and experience helps the Company drive its strategy forward and accounted for this in its succession strategy. The directors have a wide range of skills, including expertise in insurance, finance, transformation and technology. The directors’ skills, background and experience are detailed further below.

Board Diversity

Both the Board and the Governance Committee believe that Board diversity helps to ensure a balanced Board with a rounded perspective. Diversity is broadly interpreted by the Board to include viewpoints, background, attributes, experience, industry knowledge and geography. Our Board composition reflects a mix of gender, race, ethnicity, nationality, backgrounds, experiences and skill sets, including as follows: 44% of directors identify as female; 11% of directors identify as LGBT+; 11% of directors identify as Black; 66% of directors have non-U.S. citizenship; and 75% of Board Committee Chairs are female and 50% identify as Black or LGBT+.

Director Qualifications

When recommending an individual for new or continued membership on the Board, the Governance Committee considers each nominee’s individual qualifications in light of the size of the Board (which it considers appropriate), the overall mix of attributes represented on the Board, and the Company’s current and future needs. In its assessment of each nominee, the Governance Committee considers, among other things, the person’s integrity, experience, reputation, judgment, independence, maturity, skills and personality, commitment and, for current directors, tenure and performance on the Board and its Committees.

Additionally, the Governance Committee:

In assessing whether directors and director nominees have sufficient time to devote to Board duties and responsibilities, the Governance Committee considers, among other things, the number of other public company boards of directors on which a director serves as well as other commitments. The Company’s Corporate Governance Guidelines restrict the number of public company boards on which our directors may serve. None of the Company’s directors are considered “overboarded” under the Guidelines. The Board believes that each director has demonstrated the ability to devote sufficient time and attention to Board and Committee duties, and otherwise fulfill the responsibilities required of directors.

The Board evaluates each director nominee and each director’s continued service on the Board, based on his or her own merits, knowledge, experience and attributes. For this reason, the Board has not adopted a mandatory retirement age as it believes that doing so might hinder the selection or continued service of a director who would serve as an asset to the Board. However, in consideration of the Board’s recent refreshment process and the current tenures of our directors, the Board has adopted a twelve-year tenure limit for service on the Company's Board, unless the Board otherwise determines, at the recommendation of the Governance Committee, that a longer tenure for such director is in the best interest of the Company.

The Governance Committee has utilized a director skills matrix similar to the one below in its consideration of Board refreshment and director nominations. The matrix summarizes some of the experience, qualifications, attributes and skills of each individual director nominee. This summary is not intended to be an exhaustive list of each of our director nominee’s skills or contributions to the Board. Further information on each director nominee, including some of their specific experience, qualifications, attributes or skills are below under “Director Biographical Information.”

Willis Towers Watson PLC Director Skills and Experience Matrix

Board Evaluation Process

The Governance Committee considers the Board’s size, composition and effectiveness throughout the year. This includes a constructive annual evaluation process, which the Board recognizes is an essential component of good corporate governance and Board effectiveness.

The Governance Committee oversees the process and format of the evaluations of the Board and its Committees. As the process is dynamic, the format may change from year-to-year at the discretion of the Governance Committee to ensure that honest and actionable feedback is solicited and obtained from the directors. As the Board manages evolving expectations for how boards should meet their oversight duties and assess their own performance, the format of the evaluations may vary from written questionnaires completed by each director analyzed by the office of the Corporate Secretary to interviews of each director, including from time to time by a third-party facilitator.

Typically, the annual evaluation involves a multi-step process, as set forth below, that aims to generate robust comments and discussion at all levels of the Board and each Committee, with topics ranging from Board composition to processes to materials:

The evaluation process has resulted in enhancements or changes to, among other things, meeting materials, meeting topics, meeting structure, committee structure and composition and the evaluation process itself.

Director Orientation and Continuing Education

Director Orientation: Our robust orientation program familiarizes new directors with the Company’s businesses, strategies and policies, and assists new directors in developing company and industry knowledge to optimize their service on the Board. The orientation also provides new directors with an understanding of their fiduciary duties and other requirements associated with serving on the Board of an Irish-domiciled company with shares listed on NASDAQ.

Continuing Education: Regular continuing education programs enhance the skills and knowledge directors use to perform their responsibilities. These programs may include internally developed materials and presentations, programs presented by third parties, and financial and administrative support to attending qualifying academic or other independent programs.

Over the course of the last few years, the New Director Orientation and Continuing Education Program has been a standing agenda item on the Governance Committee’s agenda. The Committee has overseen the orientation of the eight new independent directors, solicited input from the directors as to how to better onboard new directors and incorporated feedback into the program.

Director Biographical Information

We have highlighted below some key qualifications, attributes, skills and experiences of each director nominee at the AGM that were considered by the Governance Committee. The absence of a particular bullet point does not mean that a director does not possess other important qualifications or skills.

Corporate Governance

We believe that good governance is critical to achieving long-term shareholder value. As such, we are committed to governance policies and practices that serve the long-term interests of the Company and its shareholders.

Corporate Governance Highlights

Board and Committee Member Independence

Based on the recommendation of the Governance Committee, the Board has determined that, with the exception of Mr. Hess, the Company's CEO, (i) each of the current directors and director nominees and (ii) each of the Board Committee members is independent under the relevant U.S. Securities and Exchange Commission (“SEC”) rules, NASDAQ listing standards and the Board’s Director Independence Standards included in the Company’s Corporate Governance Guidelines.

As discussed above, each director has significant experience and affiliations with other organizations that bring relevant expertise to the oversight of the Company. In evaluating the independence of each director, the Governance Committee considered that, in the ordinary course of business, the Company provides services (such as insurance broking or consulting services) to, or receives services from, certain organizations affiliated with the directors by virtue of directorship, employment status or share ownership. The Governance Committee determined that, in all of the above cases, the transactions do not impair the relevant director’s independence under the applicable SEC rules, NASDAQ listing standards or the Board’s Director Independence Standards.

Board Meetings and Attendance

The Board met formally eight times in 2025. Additionally, the Board and its Committees met informally with management on numerous occasions during the course of the year to discuss, among other things, strategic, operational, management, compensation and governance issues. The independent directors held separate executive sessions without management either before or after the Board’s regularly scheduled meetings in 2025. The Non-Executive Chair of the Board chaired each executive session. Neither the CEO nor any member of management at any level attends the executive sessions of the independent directors unless invited to discuss a particular matter.

All directors are expected to make every effort to attend meetings of the Board and the Board Committees on which they serve as well as each AGM. All directors who were on the Board in 2025 attended at least 75% of the aggregate number of meetings held by the Board and any Board Committee on which they served in 2025. Further, all directors participated in the 2025 AGM.

Board Leadership Structure

Our Corporate Governance Guidelines provide the Board with flexibility to choose the appropriate leadership structure for the Board based on what it believes is best for the Company at any given point in time. The Board believes that strong independent leadership is important for its performance and effectiveness and to help maintain independent oversight of management. Currently, the Board has an independent, non-Executive Chair. However, when the Board Chair and the CEO are the same individual or the Board Chair does not qualify as independent under NASDAQ rules, our Corporate Governance Guidelines provide for the appointment of a Presiding Independent Director. This structure promotes strong independence in Board leadership.

Furthermore, the Board continues to believe that the Company and its shareholders are best served by having the roles of Board Chair and CEO undertaken by different individuals. The separation allows our CEO to focus on executing our strategy and managing our business, and our Chair is able to focus on Board governance and effectiveness while providing independent Board leadership. Board committee chair roles continue to be filled by other directors, all of whom are independent and play an active role in our strategic planning and oversee such critical matters as the compensation policy for executive officers, nomination and corporate governance practices, and the integrity of financial statements and internal controls over financial reporting.

The Board generally reviews and renews, as appropriate, the term of the Board Chair annually. In furtherance of the Board's refreshment philosophy, the Board elected Paul Reilly to be the new non-executive Board Chair, effective as of the 2025 AGM.

Under the Corporate Governance Guidelines, the Non-Executive Board Chair (or the Presiding Independent Director, if any):

Willis Towers Watson Board Committees

Critical matters such as the compensation policy for executive officers, nomination and corporate governance practices, and the integrity of financial statements and internal controls over financial reporting, and enterprise-wide risk management are overseen by the Board and its Committees, which are comprised solely of independent directors.

The Board Committees, members and a description of each Committee’s function are set forth below in further detail. Each of our Board Committees has its own respective charter, which can be found, along with our Corporate Governance Guidelines in the “Investor Relations — Corporate Governance” section of our website at www.wtwco.com. Copies are also available free of charge on request from the Company Secretary.

Board Committee Composition

The current Board Committee composition is as follows:

*Designates Board Committee Chair.

General Description of Board Committee Responsibilities

The Audit Committee generally assists the Board with overseeing the following:

Given the attendant risks to the items listed above and to ensure appropriate oversight and coordination among the committees, pursuant to the Audit Committee charter, the Audit Committee coordinates with the Risk and Operational Oversight Committee (including through the Committee Chairs) regarding common areas of interest and meets jointly with that Committee to discuss some of these common areas.

The Audit Committee provides an avenue for communication among internal audit, the independent auditors, management and the Board. The members of management that join the Committee meetings include, among others, the Chief Financial Officer, the Controller, the General Counsel as well as the Heads of Internal Audit and Compliance. In addition, the Audit Committee discusses with management and, if appropriate, the independent auditors, matters such as the guidelines and policies governing the process by which senior management and the relevant departments of the Company assess and manage the Company’s exposure to risk relating to audit, financial disclosure, tax matters, pension matters and foreign exchange hedging. With respect to compliance, the Audit Committee discusses with the Chief Compliance Officer the compliance and regulatory risks of the Company and receives a report outlining the main activities of the compliance function, material regulatory interactions review, progress against the annual compliance plan and the adequacy of resources. The Committee also discusses with the General Counsel any significant legal matters that may have a material effect on the Company. There is also an overlap of members between the Audit Committee and Risk and Operational Oversight Committee to ensure proper oversight of all Company risks.

Dame Inga Beale is an audit committee financial expert, as defined by Regulation S-K, and all Audit Committee members are financially sophisticated under NASDAQ listing standards in light of their financial experience.

In 2025, the Audit Committee met formally four times. In addition to holding formal meetings, the Audit Committee members meet informally from time to time to discuss and review financial matters related to the Company and its SEC filings, including earnings releases. The Audit Committee also frequently met in executive sessions, including separate meetings with management, the internal auditors and external auditors.

The Human Capital and Compensation Committee ("HCC Committee") generally assists the Board with the following:

In 2025, the HCC Committee met formally four times. In addition to holding formal meetings, from time to time, the HCC Committee members meet informally to discuss compensation-related matters and act by unanimous written consent. After regularly scheduled meetings, the Committee also met in executive session, which included meetings with the compensation consultant.

The Governance Committee generally assists the Board with the following:

The Governance Committee believes in fostering strong governance practices and, from time to time, reviews governance principles set out by investors or other outside groups.

In 2025, the Governance Committee met formally four times. After each regularly scheduled meeting, the Governance Committee also met in executive session. In addition to holding formal meetings, the Committee members meet informally from time to time during the course of the year.

The Risk and Operational Oversight Committee generally assists the Board with the following:

Given the attendant risks to the items listed above and to ensure appropriate oversight and coordination among the committees, pursuant to the Risk and Operational Oversight Committee charter, the Risk and Operational Oversight Committee coordinates with the Audit Committee (including through the Committee chairs) regarding common areas of interest and meets jointly with that Committee to discuss some of these common areas.

In 2025, the Risk and Operational Oversight Committee met formally four times. After each regularly scheduled meeting, the Risk and Operational Oversight Committee also met in executive session. In addition to holding formal meetings, the Committee members meet informally from time to time during the course of the year. In addition to presenting to the Committee on a regular basis with respect to cybersecurity and artificial intelligence, management also presents on such matters to the Board periodically.

Director Nomination and Selection Process

The Governance Committee identifies potential director nominees by preparing a candidate profile based upon the current Board’s strengths and needs, including based on the Company’s strategy and goals for the future, and through a variety of sources, including by engaging search firms, considering input from stakeholders or utilizing the professional networks of the Board and senior management. Nominees must meet minimum qualification standards with respect to a variety of criteria including integrity, reputation, judgment, knowledge, experience, maturity, skills and personality, commitment and independence. The Governance Committee may also take into consideration additional factors that it may deem appropriate, which may include, among other factors, experience with business and other organizations, the interplay of the candidate’s experience with the experience of other Board members and the extent to which the candidate would be a desirable addition to the Board and any committee thereof.

Further, the Board believes it is important to maintain diversity among its members and is committed to the principles of diversity and inclusion, broadly interpreted to include viewpoints, background, experience, attributes, industry knowledge and geography. In recommending candidates for nomination or re-nomination to the Board, the Governance Committee will consider, in connection with director qualification criteria, the composition of the Board as a whole. During its multi-year Board succession and refreshment process, the Governance Committee considered a wide slate of potential candidates, including women as well as racially and ethnically diverse candidates.

With feedback from the Board members, members of the Governance Committee initiate contact with preferred candidates and, following feedback from interviews conducted by Governance Committee and Board members, recommend candidates to join the Board. The Governance Committee has the authority to retain a search firm to assist with this process. The Governance Committee considers candidates nominated by shareholders and ensures that such nominees are given appropriate consideration in the same manner as other candidates. Recommendations may be submitted to any member of the Governance Committee pursuant to the procedures set forth below under “Communications with Shareholders and Other Constituencies” by writing to the Company Secretary at corporatesecretary@wtwco.com.

Board Oversight of Senior Management Succession

In addition to the HCC Committee's regular review of talent and human capital management matters, the Board meets annually with the CEO and Chief Human Resources Officer to assess the succession potential and role readiness for each member of the executive leadership team. This review includes a discussion about development plans for executive officers to help prepare them for future succession and contingency plans in the event the CEO is unable to serve for any reason. Additionally, this discussion includes a review of all succession candidates for each executive officer role, including readiness assessments and related development plans for each candidate. The Chief Human Resources Officer then works with the CEO and executive officers to support candidate development.

The Board’s Role in Risk Oversight

The Company’s management is responsible for the day-to-day assessment and management of the Company’s risks. This includes identifying key risks, implementing appropriate controls, and providing regular updates to the Board and its Committees. These updates provide the Board visibility into significant risks and the mitigation strategies management employs to address them. The Board is responsible for overseeing these enterprise risk management efforts.

Board Oversight Structure

The full Board oversees the Company’s risks, including through delegating oversight of certain risks to its Committees, which report back to the Board. The full Board oversees risks related to, among other things, the Company’s long-term strategy, capital allocation, acquisitions and dispositions, crisis preparedness, and other material financial and operational matters.

Each Committee is responsible for assisting the Board with overseeing specific areas of risk, as outlined in the respective Committee Charters. The Committee Chairs regularly report to the Board on their risk oversight activities. The below is a general outline of the risks overseen by each Committee. For more information on the Board Committees, their responsibilities and areas of risk oversight, see the section above entitled “ — General Description of Board Committee Responsibilities”.

To learn more about the Company's cybersecurity risk management and strategy, the Board’s oversight framework and management’s roles and responsibilities, review the discussion in "Item 1C.Cybersecurity" included in the Company’s Annual Report on Form 10-K for the year ending December 31, 2025. See also Part I, “Item 1A, “Risk Factors” in the same report for risks facing the Company and any risk factors updated in the Company's subsequent filings with the SEC. The risks described in such filings are not the only risks facing the Company. Additional risks and uncertainties not currently known or that currently may not be considered material also may materially adversely affect the Company’s business, financial condition or results of operations in future periods.

Sustainability Oversight

Our clients, colleagues and other stakeholders expect us to conduct our business with integrity and in an environmentally and socially responsible manner. We take these expectations seriously and, consistent with what we believe enhances long-term value, have implemented sustainability programs that are aligned with our business priorities and support the communities in which we operate across the globe.

Sustainability is how we refer to our environmental, people and community, and governance efforts that relate to our own internal operations. To guide these activities, the Sustainability Taskforce is a cross-functional management committee sponsored by our General Counsel and comprised of representatives from across the global functions. The taskforce provides central governance over our sustainability efforts across the organization to ensure our activities are aligned with the Company’s business and strategic priorities. Members of the taskforce provide updates to the CEO and executive management, and meet with the Governance Committee several times a year.

With respect to Board oversight of sustainability matters, the Board believes that the most appropriate Committee should maintain oversight over relevant issues rather than concentrating the oversight of all sustainability initiatives into any one Committee. The Committees report to the Board as appropriate. For example:

To learn more about our sustainability principles, goals and related statements, and to review our Sustainability Report, Sustainability Accounting Standards Board (SASB) appendix, and Taskforce on Climate-Related Financial Disclosure (TCFD) report, visit: https://www.wtwco.com/en-us/about-us/sustainability. The information on, or accessible through, our website and the other reports is not part of or incorporated by reference into this Proxy Statement and is currently only as of the date it was first published.

Non-Employee Director Compensation

Willis Towers Watson’s non-employee director compensation takes into account, among other things, the Company’s size and complexity as well as the compensation paid by its peer companies and other similarly situated Irish-domiciled, U.S.-listed companies.

Outlined below are the fees paid to the non-employee directors for each term of service (which runs from the date of the AGM to the date of the next meeting the subsequent year) under the current Compensation Policy and Share Ownership Guidelines for Non-Employee Directors.

The following table sets forth cash and other compensation paid or accrued to the non-employee directors of Willis Towers Watson during 2025.

Share Ownership Guidelines

Under our share ownership guidelines, which are reviewed with the HCC Committee, non-employee directors are required to accumulate Willis Towers Watson shares equal to five times the directors’ annual cash retainer of $125,000 (i.e., $625,000) within eight years of their appointment to the Board. The threshold dollar amount is intended to ensure alignment with the Company’s long-term strategy and the time period is intended to attract and retain qualified new board members and candidates. Ordinary shares, deferred shares, share equivalents, RSUs and restricted shares count toward satisfying the guidelines, but options to purchase shares do not. Each director is prohibited from transferring these shares until six months after leaving Board service (other than to satisfy tax obligations on the vesting/distribution of existing equity awards), but is permitted to transfer any shares in excess of this amount. If, as a result of share price decline subsequent to a non-employee director meeting the ownership requirement, the non-employee director no longer satisfies the ownership requirement, such director is not required to buy additional shares to meet the ownership requirement. In the event a non-employee director has not met the share ownership requirement, he or she is prohibited from transferring any Willis Towers Watson shares (other than to satisfy tax obligations on the vesting/distribution of existing equity awards). In the case of financial hardship, the ownership guidelines may be waived in the discretion of the HCC Committee until the hardship no longer applies or such other appropriate time as the Committee determines. All directors have satisfied this requirement or are expected to satisfy the requirement within the appropriate timeframe.

The following table sets forth the non-employee directors’ equity ownership as of December 31, 2025.

(1) Includes 48 shares held via revocable trust.

For more information regarding the number of shares beneficially owned by each director as of March 23, 2026, see the section entitled “Additional Information — Security Ownership of Certain Beneficial Owners and Management — Directors, Director Nominees, Named Executive Officers and Other Executive Officers.”

Review and Approval of Related Person Transactions

The Company has adopted written policies and procedures governing the review and approval of transactions between the Company and any of its directors or executive officers, director nominees, any security holder who is known to the Company to own of record or beneficially more than 5% of any class of the Company’s voting securities or their immediate family members (each, a “Related Person”) to determine whether such persons have a direct or indirect material interest. The Company’s directors, director nominees and executive officers complete an annual director and officer questionnaire, which requires the disclosure of Related Person transactions. In addition, directors, director nominees and executive officers are obligated to advise the Audit Committee of any Related Person transaction of which they are aware, or become aware, and, in the event that any such transactions involve difficult or complex issues, the directors and executive officers are obligated to advise the General Counsel. Further, transactions that are determined to be directly or indirectly material to a Related Person are disclosed in the Company’s Proxy Statement or Annual Report on Form 10-K in accordance with SEC rules. The Audit Committee reviews and approves or ratifies any Related Person transaction that is required to be disclosed. In the course of its review and approval or ratification of a disclosable related person transaction, the Audit Committee considers, among other factors it deems appropriate:

Any member of the Audit Committee who is a Related Person with respect to a transaction under review may not participate in the deliberations or vote regarding the approval or ratification of the transaction, provided, however, that such director may be counted in determining the presence of a quorum at a meeting at which the Audit Committee considers the transaction.

2025 Related Person Transactions under Item 404 of Regulation S-K

BlackRock, Inc. (“BlackRock”) filed a Schedule 13G/A with the SEC reporting that, as of March 31, 2025, BlackRock and certain of its subsidiaries were beneficial owners of more than 5% of our outstanding shares. During 2025, BlackRock Advisors (UK) provided services to Willis Group Services Limited with respect to Willis Pension Trustees Limited and the UK pensions scheme trust. BlackRock received approximately $312,140 for these services, investment administration services, and software solutions, which were provided in the ordinary course of business on an arm’s-length basis.

No other transactions require disclosure under Item 404 of Regulation S-K.

Communications with Shareholders and Other Constituencies

The CEO is responsible for establishing effective communications with the Company’s stakeholder groups, including shareholders, the press, analysts, clients, suppliers, governments and representatives of the communities in which it operates. It is the policy of the Company for the CEO to appoint individuals to communicate and interact fully with these stakeholders. The Chair or another spokesperson chosen by the Board will speak for the Board when the Board determines it is appropriate for the Board to have a distinct and separate spokesperson. Often the Board will look to senior management to speak for the Company; however, the Board is also committed to engaging with shareholders to promote open and sustained dialogue in a manner consistent with the Company’s communications policies and procedures.

Non-employee directors are not precluded from communicating directly with shareholders or other constituencies about Company matters, although directors are required under the Corporate Governance Guidelines to coordinate with the Chair and senior management before doing so. An interested person may communicate with independent directors or the non-management directors as a group by writing to the Company Secretary at corporatesecretary@wtwco.com. The Company Secretary will forward the communication to the director(s) to whom it is addressed.

All communications should include the following information:

Please note that communications may be shared with Company management.

Please see the section “Additional Information — Shareholder and Other Proposals for the 2027 AGM” at the end of this Proxy Statement for shareholders seeking to present a proposal for inclusion in the Company’s proxy materials for the 2027 AGM.

Shareholder Outreach Program

The Company regularly engages with its shareholders. In addition to continuous communication throughout the year, we formally reach out to shareholders holding at least a majority of our shares in the aggregate on an annual basis, during the spring and fall seasons, and then discuss their feedback with our Board. The purpose of our formal year-round outreach is to foster relations with our shareholders by enhancing communications on corporate governance, executive compensation and sustainability topics and to provide our shareholders with a forum to discuss any questions they may have or voice any concerns. We also use the opportunity to explain various proposals included within the Proxy Statement. Members of management and directors, from time to time, participate in discussions with shareholders.

The Governance and HCC Committees are both involved in the outreach program. Generally, we review our outreach plans and the results of our outreach efforts and discuss any significant feedback with both Committees (and the full Board, as appropriate). The Committees continue to value and consider shareholder feedback and the results of the Say-on-Pay vote, among other factors, in their evaluation of the Company’s executive compensation program and corporate governance structure. We have received feedback from shareholders and have reviewed and in certain cases incorporated aspects of that feedback in parts of our Board succession plans and executive compensation programs, such as incorporating various financial metrics in executive compensation incentive plan designs.

In 2025, we reached out to shareholders holding approximately 60% of our outstanding shares, with approximately 40% of outstanding shares responding to the outreach in some manner. Shareholders were overwhelmingly supportive of the Company’s proposals, including our Say-on-Pay proposal approving our NEOs’ compensation, which received approximately 97% support at the 2025 AGM.

Vote Required for Special Meetings

Shareholders holding 10% of the Company’s share capital have the ability to convene a special meeting.

Proposal No. 2: Advisory (Non-binding) Vote to Ratify the Appointment of the Independent Auditors and a Binding Vote to Authorize the Board of Directors, Acting through the Audit Committee, to Fix the Independent Auditors’ Remuneration

For the fiscal year ending December 31, 2026, the Willis Towers Watson Audit Committee approved, and the Board ratified, the appointment of (i) Deloitte & Touche LLP, Independent Registered Public Accounting Firm, to audit the financial statements of Willis Towers Watson and (ii) Deloitte Ireland LLP, Independent Statutory Audit Firm, to audit the Irish Statutory Accounts of Willis Towers Watson. Deloitte & Touche LLP and Deloitte Ireland LLP are the respective U.S. and Irish member firms of the Deloitte Touche Tohmatsu Limited network.

We are seeking ratification of both of these appointments in a non-binding advisory vote from our shareholders at the 2026 AGM. We are not required to have our shareholders ratify the appointments of our independent auditors, but we are nonetheless doing so because we believe it to be a matter of good corporate governance practice. If our shareholders do not ratify the appointments, it will be regarded as notice to the Board and the Audit Committee to consider selecting different firms. Even if the appointments are ratified, the Audit Committee may select different independent auditors at any time if it determines that such selections would be in the best interest of Willis Towers Watson and our shareholders.

The Board unanimously recommends that you vote, on a non-binding advisory basis, “FOR” the ratification of the appointment of (i) Deloitte & Touche LLP as the Company’s Independent Registered Public Accounting Firm and (ii) Deloitte Ireland LLP as the Company’s Statutory Audit Firm for the Irish Statutory Accounts; and, on a binding basis, the authorization of the Board, acting through the Audit Committee, to fix the independent auditors’ remuneration.

A majority of the votes cast by shareholders at the 2026 AGM is required for the proposals. We expect that one or more representatives of Deloitte & Touche LLP and Deloitte Ireland LLP will be present at the 2026 AGM. Each of these representatives will have the opportunity to make a statement, if he or she desires, and is expected to be available to respond to appropriate questions.

The Audit Committee reviews the auditors’ independence and performance in deciding whether to retain them or engage different independent auditors. In the course of this review, the Committee considers, among other things, the auditors’:

Fees Paid to the Independent Auditors

The fees that the Company incurs for audit, audit-related, tax and other professional services reflect the complexity and scope of the Company’s operations, including:

The following fees have been, or will be, billed by Deloitte & Touche LLP or its respective affiliates for professional services rendered to Willis Towers Watson for the fiscal years ended December 31, 2025 and December 31, 2024 ($ in thousands).

Audit Committee Pre-Approval Process

The Audit Committee has adopted a policy regarding the pre-approval of services provided by the Company’s independent auditors, which can be found in the “Investor Relations — Corporate Governance” section of the Company’s website at www.wtwco.com. This policy requires all services provided by the Company’s independent auditors, both audit and permitted non-audit services, to be pre-approved by the (i) Audit Committee, (ii) the Audit Committee Chair or (iii) in the Chair’s absence, any other independent member of the Committee ((ii) and (iii) defined as a “designated member”). The decisions of a designated member of the Audit Committee shall be reported to the Audit Committee at its next regularly scheduled meeting.

The pre-approval of audit and permitted non-audit services may be given at any time before engagement for a specified service. Further, the policy outlines the audit and non-audit services that have been pre-approved by the Audit Committee. Pre-approval fee levels for these services to be provided by the independent auditor will be established by the Audit Committee at an annual fee meeting and pre-approved for the 12 months thereafter. All other services not listed in the policy must be specifically pre-approved by the Audit Committee or a designated member. For pre-approved services that arise between regularly scheduled Committee meetings and exceed the pre-approval fee levels set in the annual fee meeting, the Audit Committee has pre-approved an additional pre-established fee level, which is to be administered by the Controller. The Audit Committee approved all services described in the “— Fees Paid to the Independent Auditors” section above in accordance with this policy.

Audit Committee Report

The Audit Committee is currently composed of four non-employee directors: Dame Inga Beale (Chair), Fumbi Chima, Stephen Chipman and Fredric Tomczyk. Dame Inga Beale is an independent audit committee financial expert, as defined by Regulation S-K, and all Audit Committee members are considered to be financially sophisticated under NASDAQ listing standards in view of their respective financial expertise.

The Audit Committee operates under a Charter, which is described in detail under “Corporate Governance — Willis Towers Watson Board Committees.” Among its other responsibilities described in its Charter referenced above, the Audit Committee assists the Board in its oversight of the quality and integrity of the Company’s financial reporting, internal controls over financial reporting, financial management processes and risk management at the Company and subsidiary level as well the appointment, retention, performance and compensation of the Company’s independent auditor. The Audit Committee meets with members of management, including the Chief Financial Officer, the Controller, the General Counsel as well as the Heads of Internal Audit, Compliance and Risk. The Audit Committee’s focus on risk relates to major financial risk exposure, pertaining to, among other items, regulatory, litigation, audit, financial disclosure, tax matters, pension matters and foreign exchange hedging, and the steps management has taken to monitor and control such risks. Executive management is responsible for the Company’s financial statements and overall reporting process, including the system of internal controls. The independent auditors are responsible for conducting annual audits and quarterly reviews of the Company’s financial statements in accordance with auditing standards of the PCAOB and expressing an opinion as to the conformity of the annual financial statements with U.S. generally accepted accounting principles (“GAAP”). With respect to compliance, the Audit Committee discusses with the Chief Compliance Officer the compliance and regulatory risks of the Company, and the Committee receives a report outlining the main activities of the compliance function, material regulatory interactions review and progress against the annual compliance plan.

In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements as of and for the year ended December 31, 2025, with management and the independent auditors. These discussions included the quality, the clarity of the disclosures and the appropriateness of the accounting principles and underlying estimates and other communications required to be discussed under PCAOB standards. The Audit Committee has also discussed with the auditors, the auditors’ independence from Willis Towers Watson and its management, including the written disclosures and the report received from the auditors regarding the auditors’ communications with the Audit Committee concerning independence as required by the PCAOB in Rule 3526, Communication with Audit Committees Concerning Independence. The independent auditors and the Company’s internal auditors had full access to the Audit Committee, including at regular meetings without management present. It is not the duty or responsibility of the Audit Committee to conduct auditing or accounting reviews or procedures. In performing their oversight function, members of the Audit Committee rely, without independent verification, on the information provided to them and on the representations made by management and the independent auditors. Accordingly, the Audit Committee’s considerations and discussions do not assure that the audit of the Company’s financial statements has been carried out in accordance with GAAP or that the financial statements are presented in accordance with GAAP.

Based upon the review and discussions described in this report, and subject to the limitations on the role and responsibilities referred to above, the Audit Committee agreed that the audited financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC.

Proposal No. 3: Advisory (Non-binding) Vote on Named Executive Officer Compensation

Recognizing that executive compensation is an important matter for our shareholders, and in accordance with SEC rules, we are asking our shareholders to approve an advisory resolution on the compensation of our named executive officers as disclosed in this Proxy Statement.

This proposal, commonly known as a “say-on-pay” proposal, is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and our executive compensation philosophy, policies and practices as described in this Proxy Statement. Although the voting results are not binding, the Board and the HCC Committee will take into account the results of the vote when considering future executive compensation arrangements.

We encourage our shareholders to read the Compensation Discussion and Analysis, which immediately follows this proposal. The Compensation Discussion and Analysis describes in more detail our executive compensation program and related policies and practices and explains the decisions the HCC Committee has made under this program and the factors considered in making those decisions. We also encourage our shareholders to review the 2025 Summary Compensation Table and other related compensation tables and narratives, which provide detailed information on the compensation of our named executive officers.

Accordingly, we ask our shareholders to vote “FOR” the following resolution, which requires the affirmative vote of a majority of the votes cast:

“RESOLVED, that the shareholders of Willis Towers Watson Public Limited Company approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in the Company’s Proxy Statement for the 2026 AGM in accordance with the SEC’s rules, including in ‘Executive Compensation: Compensation Discussion and Analysis,’ ‘Compensation Tables — Summary Compensation Table’ and related tables and disclosure.”

The Board of Directors unanimously recommends a vote “FOR” the advisory (non-binding) resolution approving the overall executive compensation of Willis Towers Watson’s named executive officers, described in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

Executive Compensation: Compensation Discussion and Analysis

The Compensation Discussion and Analysis (“CD&A”) describes our compensation philosophy and provides an overview and analysis of (i) our 2025 compensation programs and policies for our NEOs; (ii) the material compensation decisions made by the HCC Committee under those programs and policies as reflected in the executive compensation tables that appear following this CD&A; and (iii) the material factors that the HCC Committee considered and the process it utilized in making those decisions.

2025 Incentive Plans Overview

Our incentive plans aim to align rewards with our financial performance and progress against our strategic priorities. The Company’s 2025 incentive designs remained largely consistent with 2024, with modest updates to the STI design to further emphasize accountability for financial performance results: (i) the financial performance weighting was increased to 100% for all NEOs and (ii) the weighted individual performance component was eliminated and replaced with an individual performance modifier. In addition, enterprise financial metric weightings were set consistently for all NEO roles. There were no changes to the LTIP design.
