Willis Towers Watson Public Limited Company (WTW) Stock Analysis & Winston Score

Willis Towers Watson is a global professional services firm that helps companies manage risk, attract employees, and make better business decisions. Its main services include insurance brokerage, employee benefits consulting, and data analytics. Large corporations, governments, and institutions around the world are its primary customers. The company earns money through advisory fees and commissions paid by clients when they buy insurance or use consulting services. Willis Towers Watson operates in over 140 countries and generates roughly $9–10 billion in annual revenue, making it one of the three largest insurance brokers in the world alongside Marsh McLennan and Aon. Its competitive advantage comes from deep client relationships, proprietary data, and the high cost for clients to switch providers. The key growth driver is expanding its data and technology-driven advisory services, while the main risk is losing large clients to competitors or facing fee pressure in a market where rivals are also investing heavily in analytics.
