Shareholders
Shareholders of Willis Towers Watson Public Limited Company
Willis Towers Watson Public Limited Company is a Nasdaq-listed public company, so its capital is held by public investors rather than disclosed as fixed private shareholdings on the Irish CRO record. Ownership above the disclosure threshold is instead reported through US federal securities filings identifying holders of 5 percent or more of outstanding ordinary shares. Institutional asset managers hold the substantial majority of the registered share base. The Vanguard Group is consistently reported as the largest single institutional holder, with holdings reported in the region of 10 to 12 percent of outstanding shares in aggregated institutional filings as of early 2026. BlackRock Inc and State Street Corporation are also regularly reported among the largest institutional holders, though exact current percentages vary by source and filing date. No individual person has been identified in public filings as a direct beneficial owner above the reporting threshold. Information date: institutional holdings as aggregated from filings current as of early 2026.
Data availability
Major shareholders only: direct retail shareholdings are not itemised for a Nasdaq-listed public company of this size, and disclosure is limited to institutional holders required to report beneficial ownership above regulatory thresholds under US securities law. The percentages above should be treated as approximate and time-sensitive, since institutional holdings change between quarterly filing cycles.

Directors and officers of Willis Towers Watson Public Limited Company
Current group leadership confirmed from the company’s US proxy statement includes Carl Hess, who has served as Chief Executive Officer and as a member of the Board of Directors since 1 January 2022, and Paul Reilly, who was elected Non-Executive Chair of the Board effective at the conclusion of the company’s 2025 Annual General Meeting, succeeding Paul Thomas, who had held the role since the 2022 AGM. These appointments are confirmed in the company’s Schedule 14A proxy statement filed with the US Securities and Exchange Commission and in the company’s investor relations announcements. Nationality and country of residence for these individuals are not stated here because they are not confirmed from a primary source in this research pass.
Recent officer changes
- Change of role: Paul Reilly succeeded Paul Thomas as Non-Executive Chair of the Board, effective at the conclusion of the 2025 AGM, announced 3 March 2025, per WTW SEC filings and investor relations announcements.
Data availability
Partial and historical for the Irish CRO record: the officer filing history on the CRO record for this entity dates mainly from the company’s 2009 formation and lists directors and secretaries appointed and, in most cases, resigned between 2009 and 2022; it does not reflect the company’s current board composition. Current officer and director information for this SEC-registered public company is therefore sourced from its US proxy statements rather than the CRO officer register, which does not appear to have been kept current in the underlying registry data used for this profile.

Group Structure
Group structure of Willis Towers Watson Public Limited Company
Willis Towers Watson Public Limited Company is the ultimate parent company and top level holding entity of the WTW group, and the entity registered with the US Securities and Exchange Commission as the group’s SEC registrant under CIK 0001140536. No parent company of this entity has been identified; it became the group’s top holding company following the 29 January 2016 merger of Willis Group Holdings plc and Towers Watson and Co, which combined the two predecessor organisations into the current group. Through a multi tier chain of direct and indirect subsidiaries, the group operates licensed insurance broking, reinsurance broking and consulting entities across a large number of jurisdictions, including the United States, the United Kingdom, Germany, Ireland and numerous other countries across Europe, the Americas, Asia Pacific, the Middle East and Africa. The profile’s corporate structure data already lists a large number of such subsidiaries, consistent with the scale of a global professional services group, though the individual ownership percentages and control chains for most of these entities were not independently re-verified in this research pass.
Data availability
Parent only and partial: this company’s own top of group status is confirmed by its SEC registrant status and Nasdaq listing. The extensive subsidiary listing already present in the profile has not been individually re-verified against each subsidiary’s own registry in this research pass and should be treated as indicative rather than exhaustively confirmed.
