Willis Towers Watson Plc

Willis Towers Watson Plc is a multinational insurance brokerage, risk advisory, and human capital consulting firm that generated $9.71 billion in revenue in fiscal 2025. The company operates through two segments — Health, Wealth & Career (HWC) and Risk & Broking (R&B) — serving clients across more than 140 countries from its London headquarters. It is the third-largest publicly traded insurance broker globally behind Marsh & McLennan and Aon, and occupies a distinctive niche: it combines a top-tier commercial insurance brokerage with a substantial human capital consulting practice, a pairing none of its Big Three peers replicates at comparable scale.

This is a recovery story with an AI-shaped second act. In 2021, WTW's proposed $30 billion acquisition by Aon collapsed under antitrust scrutiny, triggering a strategic reset: the company sold Willis Re to Gallagher for $3.25 billion, divested non-core assets including the direct-to-consumer Medicare business TRANZACT, and refocused around two segments whose economics are fundamentally sound—broking commissions that scale with premiums and advisory fees tied to regulatory complexity and healthcare inflation. The reset worked. FY2025 delivered $1.61 billion in net income, 25.2% adjusted operating margins, and 5% organic growth. But the valuation gap with peers remains wide: WTW trades at roughly 15 times earnings against roughly 18 times for Aon and 21 times for Marsh. The file turns on a single question: whether the company's bet on becoming "the intelligence layer for insurance" — combining proprietary data, AI-native broking tools acquired with Newfront, and an integrated operating model — can close that gap before industry structure shifts against the intermediary model.
