The lineage is two centuries of insurance and benefits businesses. Henry Willis founded the brokerage that became Willis Group in London in 1828, and it grew into one of the world's largest insurance brokers over two centuries, going through its own series of mergers and a 2007 purchase of the US broker Hilb Rogal & Hobbs.
The Towers Watson side combined three actuarial firms: Towers Perrin (1934), Watson Wyatt (1946), and the benefits consultant EMB. Towers Perrin and Watson Wyatt merged in 2010 to form Towers Watson, which then merged with Willis in January 2016 to create Willis Towers Watson.
The combined company spent its first years rationalizing a complex structure spanning insurance broking, reinsurance, retirement consulting, benefits administration, and human capital software. The Aon acquisition attempt in 2020-21 would have dissolved it into a larger rival; its collapse left the company to execute a standalone strategy.
The January 2022 rebrand to WTW, led by new CEO Carl Hess, signaled a fresh identity. Portfolio work reshaped it: the 2024 sale of TRANZACT, its direct-to-consumer Medicare insurance distribution business, removed a lower-margin operation, and the company refocused on its two core segments, Health, Wealth & Career and Risk & Broking. FY2025 revenue of $9.7 billion reflected the TRANZACT divestiture on a reported basis, down 2 percent, while organic growth of 5 percent showed the underlying business healthy.
Who owns Willis Towers Watson?
Willis Towers Watson Public Limited Company is a public company on the Nasdaq under WTW, owned by institutional investors with no controlling shareholder.
Is WTW an insurance company?
No. It is an insurance broker and advisory firm that places insurance for clients rather than underwriting it, plus human capital consulting.
What happened with the Aon merger?
Aon announced a $30 billion acquisition of WTW in 2020. The DOJ sued to block it in 2021 on antitrust grounds, and the deal was abandoned, with Aon paying WTW a $1 billion breakup fee.
How big is WTW?
Approximately $9.9 billion annual revenue, 46,000 employees, and the second-largest insurance broking business globally.
What does WTW stand for?
Willis Towers Watson, though the company rebranded to simply WTW in 2021 to unify the identity.
Who is the CEO of WTW?
Carl Hess, a company veteran who took the role in January 2022 after the Aon merger collapsed.
What are WTW's two businesses?
Risk & Broking, which is insurance broking and risk advisory, and Health, Wealth & Career, which is benefits consulting, actuarial, and talent advisory.
WTW publishes annual ESG reporting covering its own operations and increasingly advises clients on ESG and climate risk, a natural extension of its risk advisory business. It offers climate analytics and transition risk modeling to corporate clients.
Its social profile centers on human capital expertise: it sells advice on employee benefits, retirement adequacy, and workforce wellbeing, making workplace outcomes part of its product rather than just its conduct. Its gender pay and diversity reporting follows UK disclosure requirements.
The company's ethics posture is conventional for a large advisory firm, with no major environmental controversies and a clean regulatory record relative to pure financial institutions.
WTW's defining controversy was the failed Aon merger. The 2020-21 deal, which would have combined the second and third largest brokers, collapsed when the DOJ sued to block it and EU regulators demanded large divestitures. The $1 billion termination fee Aon paid softened the blow, but the episode cost WTW a year of strategic drift and management distraction.
The TRANZACT sale itself drew some scrutiny: the direct-to-consumer Medicare business had been criticized in the industry for aggressive sales practices, and its divestiture for impairment charges in 2024 removed a business that had produced both revenue and reputational questions.
Its actuarial and consulting work produces occasional litigation over pension and benefits advice, the professional liability exposure inherent to the business. No major consumer scandals attach to the brand.
