Willis Towers Watson Public Limited Company (WTW) Business Profile

What it does

Willis Towers Watson, known as WTW, advises organizations on people, risk and capital. It helps employers design benefits and retirement plans, advises on pay and workforce issues, and arranges insurance for businesses. It also provides technology, administration and investment services. Founded in 2016, WTW is headquartered in London. Carl Hess is its chief executive officer.

The company works with multinational corporations, middle-market businesses, insurers, government agencies and nonprofit institutions. Its people-related services include advising employers on health coverage, helping them manage pension costs and administering benefits for employees and retirees. WTW also operates a private U.S. Medicare marketplace that helps people compare and buy coverage.

In insurance, WTW acts as an intermediary: it advises clients on their risks, negotiates coverage and places policies with insurance carriers. It does not underwrite insurance risks for its own account. Its specialties include property and liability insurance as well as coverage for industries such as aerospace, construction, marine and natural resources.

WTW also sells advice and software to insurers, including tools for pricing and managing risk. Its investment business advises pension plans and other institutional clients and can manage assets on their behalf. Across these activities, WTW combines specialist staff, data and technology with ongoing client service.

How it makes money

WTW earns most of its revenue from brokerage commissions and fees for consulting and administration. Brokerage commissions are generally a percentage of the insurance premiums clients pay. WTW does not set those premiums, so changes in insurers’ rates can affect its commission revenue. Consulting and administration revenue comes from services performed for clients rather than from taking insured risks onto WTW’s balance sheet.

The company has two operating segments. Health, Wealth & Career provides benefits advice and broking, retirement and investment services, compensation advice and outsourced administration. It generated $5.3 billion in segment revenue in FY2025. Risk & Broking arranges business insurance and provides risk advice, as well as consulting and technology for insurers; it generated $4.2 billion in segment revenue in FY2025.

Some work recurs over long periods. Retirement clients often need annual services under multi-year contracts, while most investment revenue comes from retainer contracts. Benefits Delivery & Outsourcing earns commissions on policies sold and fees under long-term service contracts that typically run from three to five years. Career work can also be project-based and sensitive to economic conditions.

Revenue is seasonal. Company revenue is typically higher in the first and fourth quarters because of the timing of broking activity. Benefits Delivery & Outsourcing generally earns more in the fourth quarter, when annual enrollment takes place.

WTW reported $9.7 billion of revenue for the year ended December 31, 2025; its organic revenue grew 4% in the third quarter of 2026. In FY2025, reported revenue fell from $9.9 billion in the prior year, primarily because WTW sold TRANZACT, while organic revenue grew 5%.

Customers and how it sells

WTW serves clients ranging from middle-market domestic and international companies to large multinationals. Its customers also include insurers, emerging growth companies, government agencies and nonprofit institutions. Many relationships span decades, and no individual client accounted for more than 10% of consolidated revenue in 2025, 2024 or 2023.

Customers reach WTW through its advisory and brokerage teams and through technology-based services. In its Individual Marketplace, consumers can compare and buy individual and Medicare insurance products from carriers. Its outsourcing business administers health, welfare and retirement plans using technology for enrollment, benefit choices, records and self-service.

WTW serves more than 140 countries and markets. In FY2025, the United States accounted for 46.4% of revenue, the United Kingdom for 21.3%, Ireland for 1.47%, and the rest of the world for 30.9%. The geographic figures reflect where work was performed.

The company’s global network also helps it serve clients across borders. Its health and benefits business supports multinational benefit programs, while its retirement business helps employers coordinate plan design and actuarial services across global plans. WTW places insurance with approximately 2,500 carriers.

Suppliers and costs

Insurance carriers are counterparties in WTW’s brokerage business: WTW places clients’ insurance with approximately 2,500 carriers. No individual carrier accounted for a significant concentration of the total premiums WTW placed for clients in 2025, 2024 or 2023. Carriers set the premiums on which commissions are generally based.

WTW’s work depends on employees with consulting, actuarial, broking, technology and other specialist skills. It had 46,900 employees at December 31, 2025. Its operating costs are affected by labor costs and by the expense of running and investing in the business. WTW also invests in technology and infrastructure, including partnerships with technology companies; those investments can require significant capital expenditures.

The company’s obligations include operating leases, debt and interest payments, and pension obligations and contributions. WTW is also investing in Propel, its AI acceleration plan. It expects to invest approximately $625 million in cash under the plan to deliver approximately $400 million of annual run-rate savings by the end of 2028, before reinvestment for growth.

Competitive position

WTW competes across its businesses on factors including global reach, breadth of services, innovation, service quality and price. Named competitors include Aon, Arthur J. Gallagher, Brown & Brown and Marsh & McLennan, alongside specialty, regional and local firms.

In pension consulting, WTW identifies Aon and Mercer, a Marsh & McLennan company, as its largest competitors. In insurance exchanges, it names Aon, Mercer, Automatic Data Processing and Fidelity among its largest competitors, as well as public exchanges. Insurance consulting and software competitors include Milliman, Oliver Wyman and the big four accounting firms.

Competition also comes from alternatives to buying insurance through a broker. Some customers retain more risk themselves or use captive insurers and other risk-funding arrangements. Banks, accounting firms, new brokers and insurance carriers also offer risk-management or risk-transfer services.

Our reading: WTW’s long client relationships and recurring retirement and administration contracts offer a meaningful source of customer retention, although some consulting work remains project-based. Our reading: Its international reach and specialist expertise support competition for complex multinational work, but large rivals also compete in pension consulting and exchanges. Our reading: Proprietary data and technology can reinforce its services, though technology markets remain competitive and require continued investment.

Growth opportunities

WTW’s strategy focuses on growing its existing businesses, improving efficiency and investing in areas including corporate risk and broking, health and benefits, and wealth. It also seeks to optimize its portfolio through acquisitions and divestitures. WTW completed its Newfront acquisition in January 2026; it later said the Newfront and Cushon integrations were on track.

The company is expanding technology across client services and internal operations. Its Propel plan includes AI-enabled workflows in benefits administration, actuarial work and insurance broking. WTW expects the program to support an adjusted operating margin of approximately 30% in 2028, alongside investment and reinvestment for growth.

In the Individual Marketplace, WTW sees an opportunity to help employers move retirees from group coverage to individual policies. It estimates that 12 million retirees are covered by group plans that could be replaced by individual marketplace policies. WTW said sales would add more than 100,000 retirees to its existing base of 1.2 million, but three large clients with 75,000 retirees postponed implementation into 2027.

WTW also has a minority stake in the Willis Re reinsurance broking joint venture, with an option to acquire control. Willis Re agreed to acquire BMS Re’s U.S. reinsurance broking business, subject to regulatory approval. WTW expects to make capital contributions to the venture while it builds revenue.

Structural risks

• Insurance pricing: Brokerage commissions generally follow premiums. A soft market with lower premium rates can put downward pressure on commission revenue and operating margin. WTW said commercial insurance rates continued to soften in the third quarter of 2026, although U.S. casualty rates continued to rise.
• Discretionary demand: Economic conditions can make clients more cautious about discretionary services or lead them to use alternatives such as self-insurance. WTW said a softer labor market and conditions in the Middle East were weighing on project work in parts of its Career business.
• Regulation and liability: WTW operates under insurance, investment, privacy and other rules across many jurisdictions. Compliance failures can lead to fines, reputational damage and financial harm; claims and lawsuits arising from its work can also adversely affect the business.
• People and technology: The company depends on senior leaders and skilled employees. Data or cybersecurity breaches and improper disclosure of confidential information could lead to financial loss, regulatory action, reputational harm or legal liability.
• Execution and financial obligations: Technology and infrastructure investments may not produce the expected returns, and failure to execute the company’s strategy could affect results. Material pension liabilities can fluctuate, while debt payments can limit cash available for investment and other purposes.

Bottom line

Our reading

WTW combines an insurance intermediary with recurring benefits, retirement and investment services, alongside more discretionary consulting work. Its long relationships and service contracts provide recurring activity, but commissions remain exposed to insurance pricing and some projects can be deferred. Growth initiatives in technology, acquisitions and reinsurance require investment and execution while the company manages regulatory, personnel and pension risks.
