Overview
Willis Towers Watson plc, commercially branded as WTW, is a British-American global advisory, broking and solutions company legally domiciled in Ireland and principally managed from London. Its business combines insurance brokerage, risk advisory, employee benefits, retirement and actuarial consulting, investment advice, benefits administration, human-capital consulting and insurance technology. WTW serves corporations, financial institutions, public-sector organizations, insurers, pension schemes and other institutional clients. It is one of the largest insurance brokerage and risk-advisory groups by revenue and competes internationally with firms such as Aon, Marsh McLennan and Arthur J. Gallagher & Co. The modern company was created in January 2016 through the combination of Willis Group and Towers Watson. Willis brought a long-established insurance-broking and risk-management heritage, while Towers Watson contributed actuarial, retirement, employee-benefits, investment and human-resources consulting capabilities. The merger was structured as a combination of equals and initially operated under the name Willis Towers Watson, with shares trading on Nasdaq under the symbol WLTW. The company became an S&P 500 constituent soon after the transaction. WTW organizes its operations into two broad segments. Risk & Broking provides commercial insurance brokerage, specialty broking, risk management, risk-financing advice and insurance consulting and technology. Its work includes helping clients identify exposures, design insurance programs, place coverage with insurers and manage claims or related risk processes. The insurance consulting and technology activities also supply analytical and software tools for pricing, reserving, capital modeling and other insurer functions, including the Radar, ResQ and Igloo platforms. Health, Wealth & Career covers health and benefits brokerage, benefits administration and technology, retirement and actuarial consulting, investment advice for pension funds and institutional investors, and human-capital, talent, rewards and workforce consulting. The segment addresses both the financial architecture of employee programs and the broader relationship between organizational design, rewards, wellbeing, performance and talent. In the United Kingdom, WTW sponsors LifeSight, a regulated defined-contribution master trust for participating employers. The company’s attempted acquisition by Aon became one of the defining events in its early history. Aon announced an all-stock proposal valued at approximately $30 billion in March 2020. Regulators in several jurisdictions reviewed the transaction because it would have combined two of the three largest global insurance brokers. The United States Department of Justice sued to block the deal in June 2021, alleging that the combination would reduce competition in several large-client broking, reinsurance, benefits and pension-administration markets. Aon and WTW terminated the agreement on July 26, 2021, and Aon paid WTW a $1 billion termination fee. WTW subsequently divested treaty reinsurance operations to Arthur J. Gallagher & Co. as part of the regulatory-remedy process. WTW adopted the shorter WTW brand commercially in January 2022 and changed its Nasdaq symbol from WLTW to WTW. The rebrand emphasized a unified identity across people, risk and capital services while retaining the underlying Willis Towers Watson plc legal name. Since then, the company has pursued a strategy combining organic growth, technology investment and targeted acquisitions. Its transactions have included climate-risk consultancy Acclimatise, climate analytics firm Butterwire, Israeli broker Leaderim, the United Kingdom workplace-savings provider Cushon, Canadian trade-credit specialist Invoice Cover, United States broker Newfront and FlowStone Partners. As of 2026, WTW remains an active publicly traded professional-services and financial-services company. Its principal executive offices remain at the Willis Building in London, while its registered corporate domicile is in Ireland. The company’s current strategic emphasis is on integrated advice across people, risk and capital, technology-enabled broking, specialty and middle-market expansion, data and analytics, employee financial wellbeing, retirement outcomes, organizational performance and resilience against climate, cyber, geopolitical and other complex risks.
History
WTW’s history is assembled from several strands of insurance broking, actuarial work, employee-benefits consulting and human-capital advisory. The oldest predecessor associated with the Willis lineage dates to Henry Willis’s insurance-broking activities at Lloyd’s in the nineteenth century. Henry Willis & Co. later combined with Faber Brothers in 1898 to form Willis, Faber & Co., and with Dumas & Wylie in 1928 to form Willis, Faber & Dumas. The business became a public company on the London Stock Exchange in 1976. Willis entered the U.S. retail-broking market in 1990 through a merger with Corroon & Black, creating Willis Corroon. The company was taken private by KKR in 1998, adopted the Willis Group name and returned to public markets in 2001, listing on the New York Stock Exchange under WSH. Its subsequent development combined geographic expansion with acquisitions and specialist capabilities. Willis acquired Hilb, Rogal & Hobbs in 2008, strengthening its North American network, and expanded its French presence through Gras Savoye. It also agreed in 2015 to acquire an 85 percent stake in London broker Miller. In 2006, it launched the Willis Research Network to connect academic research with insurance and risk-management practice, particularly in areas such as natural hazards and catastrophe risk. The Towers Watson lineage developed from two principal consulting traditions. R. Watson & Sons was founded in the United Kingdom in 1878 and became associated with actuarial and pension work. The Wyatt Company was established in the United States in the 1940s. The two businesses combined through a 1995 transaction and later formalized their international integration as Watson Wyatt Worldwide in 2005. Watson Wyatt had become publicly traded in the United States in 2000. A separate predecessor, Towers, Perrin, Forster & Crosby, was established in the United States in 1934. It acquired actuarial consultancy Tillinghast, Nelson & Warren in 1986 and shortened its name to Towers Perrin in 1987. Towers Perrin and Watson Wyatt completed a merger of equals on January 4, 2010, creating Towers Watson under the leadership of John Haley. The resulting firm provided employee benefits, talent and rewards, retirement, investment, risk and capital-management services. Its expansion included the acquisition of EMB Consultancy in 2011, Extend Health in 2012, Liazon in 2013, Acclaris in 2015 and Brovada Technologies in 2015. It also sold its reinsurance brokerage business to Jardine Lloyd Thompson in 2013 and its human-resources service-delivery practice to KPMG in 2015. Willis Group and Towers Watson announced their own combination in 2015. Shareholders approved a revised transaction in December 2015 after an earlier vote failed to secure sufficient support. The merger completed in early January 2016, creating Willis Towers Watson plc. The new company combined Willis’s commercial and specialty insurance broking with Towers Watson’s consulting, actuarial, benefits, investment and human-capital operations. Its shares initially traded on Nasdaq under WLTW, and the company was subsequently included in the S&P 500. The proposed Aon acquisition became the company’s most consequential strategic challenge after its formation. Announced on March 9, 2020, the all-stock proposal was valued at roughly $30 billion. Regulators viewed the transaction as potentially eliminating important competition between two of the global insurance industry’s largest brokers. The European Commission conducted an in-depth review and approved the deal conditionally in July 2021, while the Australian Competition and Consumer Commission raised preliminary concerns. The U.S. Department of Justice filed a civil antitrust action on June 16, 2021, alleging harm in five markets. Aon and WTW terminated the agreement on July 26, 2021, with Aon paying a $1 billion fee. WTW then divested treaty reinsurance operations to Arthur J. Gallagher & Co. and continued as an independent company. During this period WTW also acquired Acclimatise, a climate consultancy, and later Butterwire, a climate-risk analytics firm. In January 2022 it consolidated its commercial identity under the WTW name and changed its Nasdaq ticker to WTW. It withdrew from Russia in 2022 by transferring ownership of its Russian businesses to local management. Later strategic activity included the planned sale of TRANZACT, a direct-to-consumer unit, completion of that sale in January 2025, the agreement to acquire Cushon from NatWest Group in December 2025, the acquisition of Québec-based Invoice Cover, the purchase of Newfront, and the completion of FlowStone Partners. These moves reflect a continuing effort to concentrate the portfolio on advisory, broking, retirement, employee benefits, technology and institutional solutions. Governance has also evolved. Carl Hess became chief executive officer on January 1, 2022, succeeding John Haley. Andrew Krasner became chief financial officer in 2021. Paul Reilly became non-executive chair in May 2025, succeeding Paul Thomas. By 2026 WTW remained an Irish public limited company with principal executive offices in London and a broad international operating footprint.
